[0081] The flexible and dissolvable sheet may contain a polyvinyl alcohol (PVA) polymer or a copolymer thereof as a film former, a structurant, and a carrier for surfactants and optionally other active ingredients (e.g., emulsifiers, builders, chelating agents, fragrances, colorants, etc.). It is preferred that the PVA polymer or copolymer is present in the flexible and dissolvable sheet in an amount ranging from about 5% to about 50%, preferably from about 10% to about 40%, preferably from about 15% to about 30%, and more preferably from about 20% to about 25%, based on the total weight of the solid sheet. In a particularly preferred embodiment of the present invention, the total amount of one or more PVAs present in the flexible and dissolvable solid sheet article of the present invention is not more than 25% by weight of such sheet article.
[0082] PVA polymers or copolymers suitable for the practice of the present invention are selected from those having a weight average molecular weight in the following range: about 50,000 Daltons to about 400,000 Daltons, preferably about 60,000 Daltons to about 300,000 Daltons, more preferably about 70,000 Daltons to about 200,000 Daltons, and most preferably about 80,000 Daltons to about 150,000 Daltons. The weight average molecular weight is calculated by calculating the sum of the products of the average molecular weight of each polymer raw material and their corresponding relative weight percentages based on the weight of the total weight of the polymer present in the porous solid.
[0083] Flexible and dissolvable solid sheets are preferably prepared by first forming a wet premix comprising PVA, a surfactant and optionally other active ingredients, then forming the wet premix into a sheet, and then drying such wet premix sheet to form a solidified sheet product. Correspondingly, the weight average molecular weight of the PVA polymer or copolymer can affect the overall film-forming properties of the wet premix and its compatibility / incompatibility with the desired surfactant. In addition, the weight average molecular weight of the PVA polymer or copolymer used herein may affect the viscosity of the wet premix, which in turn may affect various physical properties of the resulting solid sheet product so formed.

Each ply within the fiber structure may include one or more layers that together form the ply. A layer may include a plurality of fiber elements.
[0085] The fibrous structure may comprise at least one fabric hueing agent between the first ply and the second ply. The unit dose article may comprise a surfactant. In one non-limiting example, the fibrous structure may comprise a surfactant between the first ply and the second ply. In one non-limiting example, the first ply and / or the second ply and / or any other ply may comprise a surfactant.
[0086] The water-soluble fiber unit dose product 1 can dissolve under various washing conditions, for example, low temperature, low water and / or short washing cycle, and / or cycle in which the consumer has overloaded the machine. The unit dose product 1 of the present invention may contain one or more active agents. As used herein, "active agent" refers to any ingredient that can directly or indirectly provide a beneficial effect to one or more fabrics. The water-soluble unit dose product 1 may contain an insoluble material that can be dispersed into a suspension under aqueous washing conditions, with an average particle size of less than about 20 microns, or less than about 50 microns. The particles may be particles containing active substances. The advantage of such unit dose products 1 of the present invention is that the unit dose product 1 will be completely dissolved in the aqueous solution, so that any active agent contained in the unit dose product 1 is released into the washing liquid instead of remaining in the substrate of the unit dose product 1. Another advantage of the unit dose product 1 of the present invention is the direct quantitative unit dose product 1, so that consumers can place one or more unit dose products 1 in the drum of the washing machine without measuring the product.
[0087] The water-soluble unit dose article may exhibit a thickness of greater than 0.01 mm and / or greater than 0.05 mm and / or greater than 0.1 mm and / or to about 100 mm and / or to about 50 mm and / or to about 20 mm and / or to about 10 mm and / or to about 5 mm and / or to about 2 mm and / or to about 0.5 mm and / or to about 0.3 mm as measured by the Thickness Test Method described herein. In a preferred but not essential embodiment of the present invention, the unit dose article 1 of the present invention has a rectangular or kite shape. Such rectangular or kite shapes are aesthetically pleasing and pleasing to consumers, so multiple articles of such shapes can be stacked and packaged together for sale in containers also having similar rectangular or kite shape features.
[0088] The water-soluble unit dose article may have a Basis Weight of about 500 grams / m2 as measured according to the Basis Weight test method described herein. 2 to about 5,000 g / m 2 , preferably about 1,000 g / m 2 About 4,000 g / m 2 , more preferably about 1,500 g / m 2 About 3,500 g / m 2 , most preferably about 2,000 g / m 2 About 3,000 g / m 2 The basis weight.

[0096] The composition may comprise one or more amphiphilic cleaning polymers. Such polymers have balanced hydrophilicity and hydrophobicity so that they remove grease particles from fabrics and surfaces. Suitable amphiphilic alkoxylated grease cleaning polymers include a core structure and a plurality of alkoxylate groups attached to the core structure. These may comprise alkoxylated polyalkyleneimines, especially ethoxylated polyethyleneimines or polyethyleneimines having internal polyethylene oxide blocks and external polypropylene oxide blocks. Typically, these may be incorporated into the composition of the present invention in an amount of 0.005 wt % to 10 wt %, typically 0.5 wt % to 8 wt %.
[0097] The fabric and home care products of the present disclosure may include additional surfactants. The additional surfactants may be used to provide, for example, cleaning benefits. The fabric and home care products may include a surfactant system, which may include one or more surfactants.
[0098] The fabric and home care products of the present disclosure may contain from about 0.1% to about 99%, or from about 2% to about 80%, or from about 5% to about 75% of the surfactant system by weight of the composition. Liquid compositions may contain from about 5% to about 40% of the surfactant system by weight of the composition. Compact formulations, including compact liquids, gels and / or compositions suitable for unit dosage forms, may contain from about 25% to about 70% or from about 30% to about 50% of the surfactant system by weight of the composition.
[0099] The surfactant system may include anionic surfactants, nonionic surfactants, zwitterionic surfactants, cationic surfactants, amphoteric surfactants, or combinations thereof. The surfactant system may include linear alkylbenzene sulfonates, alkyl ethoxylated sulfates, alkyl sulfates, nonionic surfactants such as ethoxylated alcohols, amine oxides, or mixtures thereof.

[0100] Suitable anionic surfactants may include any conventional anionic surfactants. This may include sulfate detersive surfactants (e.g., alkoxylated and / or non-alkoxylated alkyl sulfate materials) and / or sulfonic acid detersive surfactants (e.g., alkylbenzene sulfonates). Anionic surfactants may be linear, branched, or combinations thereof. Preferred anionic surfactants include linear alkylbenzene sulfonates (LAS), alkyl ethoxylated sulfates (AES), alkyl sulfates (AS), or mixtures thereof.

[0101] Fabric and home care products may also include branched alkyl sulfate surfactants. Branched alkyl sulfates may include 2-alkyl branched alkyl alcohols. 2-alkyl branched alcohols are positional isomers in which the position of the hydroxymethyl group (composed of a methylene bridge (-CH2-unit) connected to a hydroxyl (-OH) group) on the carbon chain is different. Therefore, 2-alkyl branched alkyl alcohols are generally composed of a mixture of positional isomers. In addition, it is well known that fatty alcohols (such as 2-alkyl branched alcohols) and surfactants are characterized by chain length distribution. In other words, fatty alcohols and surfactants are generally composed of a blend of molecules with different alkyl chain lengths (although a single chain length cutoff can be obtained). It is noteworthy that the 2-alkyl primary alcohols described herein cannot be obtained by simply blending commercially available materials, which may have a specific alkyl chain length distribution and / or a specific fraction of certain positional isomers. Specifically, the distribution of surfactants having m+n=11 of about 50% to about 100% by weight cannot be achieved by blending commercially available materials.
[0102] The branched alkyl sulfate may consist essentially of a mixture of surfactant isomers of Formula 3 and a surfactant of Formula 4:
[0103] Formula 3:
[0104] Formula 4: CH3-(CH2) m+n+3 -X
[0105] wherein about 50% to about 100% by weight of the first surfactant is an isomer having m+n=11; wherein between about 25% to about 50% of the mixture of surfactant isomers of formula 3 has n=0; wherein about 0.001% to about 25% by weight of the first surfactant is a surfactant of formula 4.
[0106] Surfactant system can comprise nonionic surfactant.Suitable nonionic surfactant comprises alkoxylated fatty alcohol, such as ethoxylated fatty alcohol.Other suitable nonionic surfactant comprises alkoxylated alkylphenol, alkylphenol condensate, mid-chain branched alcohol, mid-chain branched alkyl alkoxylate, alkyl polysaccharide (for example, alkyl polyglycoside), polyhydroxy fatty acid amide, ether-terminated poly (alkoxylated) alcohol surfactant and their mixture.Alkoxylate unit can be ethyleneoxy unit, propyleneoxy unit or their mixture.Nonionic surfactant can be linear, branched (for example, mid-chain branched) or their combination.Specific nonionic surfactant can comprise alcohol with average about 12 to about 16 carbon atoms and average about 3 to about 9 ethoxy groups, such as C12-C14 EO7 nonionic surfactant.
[0107] The nonionic surfactant may have the formula R(OC2H4)n OH, wherein R is selected from the group consisting of aliphatic hydrocarbon groups containing from about 8 to about 16 carbon atoms, and n has an average value of from about 5 to about 15. For example, the nonionic surfactant can be selected from ethoxylated alcohols having an average of about 12 to 14 carbon atoms in the alcohol (alkyl) portion and an average degree of ethoxylation of about 7-9 moles of ethylene oxide per mole of alcohol.
[0108] Additional non-limiting examples include the formula R(OC2H4) n OH ethoxylated alkylphenols wherein R comprises an alkylphenyl group wherein the alkyl group comprises from about 8 to about 12 carbon atoms and n has an average value of from about 5 to about 15, C12-C18 alkyl ethoxylates such as those from Shell Nonionic surfactant; C 14 -C 22 Mid-chain branched alcohol; C 14 -C 22 Medium Chain Branched Alkyl Ethoxylate, BAE x , wherein x is 1 to 30. The nonionic ethoxylated alcohol surfactants herein may also contain residual alkoxylation catalysts, which may be considered as residues or impurities of the reaction. It may also contain various impurities or by-products of the alkoxylation reaction. The impurities may vary depending on the catalyst used and the reaction conditions. Impurities include alkyl ethers, such as dialkyl ethers, such as didodecyl ether; glycols, such as diethylene glycol, triethylene glycol, pentaethylene glycol, other polyethylene glycols.
[0109] The nonionic ethoxylated alcohol may be a narrow range ethoxylated alcohol. The narrow range ethoxylated alcohol may have the following general formula (5):
[0110]
[0111] Wherein R is selected from saturated or unsaturated, linear or branched C8-C 20 alkyl groups, and wherein greater than 90% of n is 0≤n≤15. In addition, the average value of n may be between about 4 and about 14, preferably between about 6 and about 10, wherein less than about 10% by weight of the alcohol ethoxylates are ethoxylates with n<7, and between 10% by weight and about 20% by weight of the alcohol ethoxylates are ethoxylates with n=8.
[0112] The composition may comprise an average value of n of about 10. The composition may have the following ranges for each of the following n: n=0 is up to 5%, each of n=1, 2, 3, 4, 5 is up to 2%, n=6 is up to 4%, n=7 is up to 10%, n=8 is between 12% and 20%, n=9 is between 15% and 25%, n=10 is between 15% and 30%, n=11 is between 10% and 20%, n=12 is up to 10%, and n>12 is up to 10%. The composition may have between 30% and 70% of n=9 to 10. The composition may have greater than 50% of its composition consisting of n=8 to 11.
[0113] R is selected from saturated or unsaturated, linear or branched C12-C16 alkyl groups, wherein the average value of n is between about 6 and about 10. R may also be selected from saturated or unsaturated, linear or branched C8-C 20 Alkyl groups, wherein more than 90% of n is 0≤n≤15, and wherein the average value of n is between about 5 and about 10, wherein less than about 20% by weight of the alcohol ethoxylates are ethoxylates with n<8. R may also be selected from saturated or unsaturated, linear or branched C8-C 20 Alkyl groups wherein greater than 90% of n is 0≤n≤15, and wherein the average value of n is between about 6 and about 10, wherein less than about 10% by weight of the alcohol ethoxylates are ethoxylates with n<7, and between 10% by weight and about 20% by weight of the alcohol ethoxylates are ethoxylates with n=8.
[0114] The alcohol ethoxylates described herein are generally not a single compound as shown in their general formula (5), but rather they comprise a mixture of several homologs having different polyalkylene oxide chain lengths and molecular weights. Among the homologs, those having a total number of alkylene oxide units per mole of alcohol that is closer to the most common alkylene oxide adducts are ideal; homologs having a total number of alkylene oxide units that is much lower or much higher than the most common alkylene oxide adducts are less ideal. In other words, a "narrow range" or "peaked" alkoxylated alcohol composition is ideal. A "narrow range" or "peaked" alkoxylated alcohol composition refers to an alkoxylated alcohol composition having a narrow distribution of mole numbers of alkylene oxide additions.
[0115] A "narrow range" or "peaked" alkoxylated alcohol composition may be ideal for a selected application. Homologs within a selected target distribution range may have an appropriate lipophilic-hydrophilic balance for a selected application. For example, in the case of an ethoxylated alcohol product comprising an average ratio of 5 ethylene oxide (EO) units per molecule, homologs having a desired lipophilic-hydrophilic balance may be in the range of 2EO to 9EO. Homologs having shorter EO chain lengths (<2EO) or longer EO chain lengths (>9EO) may be undesirable for applications where surfactants with an EO / alcohol ratio of 5 are typically selected, because such longer and shorter homologs are too lipophilic or too hydrophilic for the application utilizing the product. Therefore, it is advantageous to develop alkoxylated alcohols with a peaked distribution.
[0116] The narrow range alkoxylated alcohol compositions of the present disclosure may have an average degree of ethoxylation of from about 0 to about 15, such as from about 4 to about 14, about 5-10, about 8-11, and about 6-9. The narrow range alkoxylated alcohol compositions of the present disclosure may have an average degree of ethoxylation of 10. The narrow range alkoxylated alcohol compositions of the present disclosure may have an average degree of ethoxylation of 9. The narrow range alkoxylated alcohol compositions of the present disclosure may have an average degree of ethoxylation of 5.
[0117] The above ranges are exemplified in Table A in column Novel 1214-9. As shown in Table A below, samples were analyzed by LCMS ESI (-) and by LCMS ESI (+) after derivatization with DMF-SO3 complex. The % relative abundance is listed in the table below. The percent relative abundance is the weighted average of each ethoxymer relative to the total abundance of all ethoxymers in the sample.
[0118] Table A
[0119] Number of moles of EO Alfonic 1214-9 Novel 1214-9 0 3.14% 2.33% 1 1.26% 0% 2 1.55% 0% 3 2.20% 0% 4 3.08% 0.39% 5 4% 0.940% 6 5.21% 2.93% 7 6.58% 7.90% 8 8.10% 15.96% 9 9.41% 21.56% 10 9.78% 21.27% 11 9.51% 15.19% 12 8.58% 7.64% 13 7.35% 2.84% 14 5.98% 0.88% 15 4.65% 0.18% 16 3.46% 0% 17 2.48% 0% 18 1.74% 0% 19 1.17% 0% 20 0.75% 0%
[0120] Note that LCMS-ESI (+) is not sensitive to ethoxymers less than 3 moles, nor is the free alcohol. In addition, ethoxymers between 3-5 moles are not adequately represented. Typically, if the average distribution of EO is greater than 7 moles EO, the distribution is not greatly affected by this sensitivity limit. In addition, when the distribution is very broad, as in the ALFONIC sample, LCMS-ESI (-) can underestimate heavier ethoxymers. For this reason, the ALFONIC sample was analyzed in both + / - modes and averaged.
[0121] Suitable zwitterionic surfactants may include any conventional zwitterionic surfactants such as betaines, including alkyl dimethyl betaine and cocodimethylamidopropyl betaine, C8 to C 18 (For example, C12 To C 18 ) amine oxides (e.g., C 12-14 dimethylamine oxide), and / or sulfobetaines and hydroxybetaines, such as N-alkyl-N,N-dimethylamino-1-propanesulfonates, wherein the alkyl group can be C8 to C 18 or C 10 To C 14 The zwitterionic surfactant may include an amine oxide.

[0151] data
[0152] Compositions having surfactants of formula I as described above were tested to determine whether there was an advantage in using them in terms of stain removal. To observe the stain removal effect, a technical stain removal washing procedure was used. The method is described below.
[0153] Several different stain types were reviewed as shown in Table 1 below. The results show that the use of surfactants of Formula I (inventive compositions BD, Examples section) has better or equal stain removal than conventional liquid detergent compositions such as sodium lauryl sulfate surfactant in Comparative composition A (Examples section).
[0154] Table 1
[0155]
[0156] The technical stain removal wash procedure was followed as described below. 0.66 grams of soluble unit dose detergent EH was added to an oscillating detergent jar containing 1 L of test wash solution plus test fabric, soiled SBL fabric, and clean fabric ballast, agitated at 208 rpm for 17 minutes at 15°C and 7 US grains / gallon and spun dry. The fabric was then rinsed at 200 rpm for 5 minutes in 15°C water and 7 US grains / gallon and spun dry. After rinsing, the fabric was machine dried in the high efficiency mode for 40 minutes before analysis.
[0157] The stain removal index score for each stain was calculated as described below and is listed below in Table 2. These results show that the use of surfactants of Formula I (present compositions FG, Examples section) has better or equal stain removal than branched C15 alkyl sulfate surfactants in soluble unit dose detergents (such as Comparative Composition E (Examples section)).

[0159]
[0160] method
[0161] Technical stain removal washing program
[0162] The method involves the use of an oscillating detergent to simulate fabric washing in a washing machine. Technically soiled swatches (9 grams) were washed with soiled SBL fabric (4 grams) and clean knitted cotton ballast (47 grams) using the test formulation. Technically soiled swatches of CW120 cotton containing the stain were purchased from Advanced Product Design Co., Inc (Cincinnati, OH). Wash testing consisted of two internal and four external replicates for each stain type and treatment.
[0163] 2.37 grams of liquid detergent AD (Comparative Composition A and Inventive Composition BD below) were added to an oscillating detergent jar containing 1 L of test wash solution plus a ballast of test fabrics, soiled fabrics, and clean fabrics, agitated at 208 rpm for 17 minutes at 15°C and 7 US grains / gallon and spun dry. The fabrics were then rinsed at 200 rpm for 5 minutes at 15°C water and 7 US grains / gallon and spun dry. After rinsing, the fabrics were machine dried in the high efficiency mode for 40 minutes before analysis.
[0164] Image analysis was used to compare each stain to an unstained fabric control. The software converted the captured images into standard colorimetric values and compared these to standards based on the commonly used Macbeth color reproduction chart, assigning a colorimetric value (stain content) to each stain. Two internal replicates and four external replicates were prepared for each.

In methods for preparing such compositions, a liquid matrix can be formed that contains at least a majority or even substantially all of the liquid components, e.g., surfactants, non-surfactant liquid carriers, and other optional liquid components, while the liquid components are thoroughly mixed by applying shear agitation to the liquid combination. For example, rapid stirring with a mechanical stirrer can be effectively employed.

[0215] Example of a fiber-based water-soluble unit dose
[0216] The fiber water-soluble unit metering of the fiber containing the first layer of fiber elements is spun and collected on a forming belt using a first spinning manifold. Then, the forming belt with the first fiber layer is passed under the second spinning manifold, and the second spinning manifold is modified with a particle addition system. The particle addition system can basically spray particles into a landing zone on the forming belt, which is directly located below the fiber elements from the second spinning manifold. A suitable particle addition system can be assembled by a particle feeder such as a vibrator, a belt or a screw feeder and an injection system such as an air knife or other fluidized conveying system. In order to contribute to the uniform distribution of particles in the lateral direction, it is preferred that the particle feed is approximately the same width as the spinning die to ensure that the particles are delivered through the entire width of the composite structure. Preferably, the particle feeder is completely closed except for the outlet to minimize the damage of the particle feed. The joint impact of particles and fiber elements on the forming belt below the second spinning manifold produces a composite structure, wherein the particle filler is expanded and the fiber substantially penetrates the inter-particle pores.
[0217] The following charts show non-limiting examples of dry fiber compositions that can be used to prepare fibrous elements. To prepare the fibrous elements, an aqueous solution preferably having a solids content of about 45% to 60% is processed through one or more spinning beams. A suitable spinning beam includes a capillary die having a decaying air flow and a drying air flow suitable for substantially drying the decaying fibers before they impact the forming belt.

[0248] The starting materials Ar-COOH (II) and R3-CH2-COOH (III) used in the process of the present invention are commercially available or can be synthesized by a person skilled in the art in view of his / her common general knowledge.
[0249] Decarboxylation cross ketone is preferably carried out in the form of catalytic decarboxylation cross ketone. Such procedures are known from WO 2018 / 229285A1 (see, for example, page 4, lines 9-34 of WO 2018 / 229285 A1). As described in detail in WO 2018 / 229285A1, catalytic decarboxylation cross ketone of aromatic carboxylic acid and aliphatic carboxylic acid can be similarly applied in the context of this article to provide arylaliphatic ketone of formula IV: Ar-C(=O)-CH2-R3(IV).

[0251] Alternative a.: Steps b. and c. - Hydrogenation - Sulfation - Neutralization
[0252] In the following, the hydrogenation-sulfation sequence of steps b. and c. according to alternative a. of the process will be further described.
[0253] Step b. of alternative a.: In the process according to alternative a., an aromatic aliphatic ketone of formula IV: Ar-C(=O)-CH2-R3 (IV) is hydrogenated in the presence of H2 and a catalyst to obtain a secondary alcohol of formula V: Ar-CH(OH)-CH2-R3 (V), wherein Ar and R3 are as defined above and in the claims.
[0254] The catalytic hydrogenation of arylaliphatic ketones to give the corresponding arylaliphatic alcohols is a standard reaction known to the person skilled in the art.
[0255] In this process, the hydrogenation step is carried out in the presence of a metal-based catalyst, preferably a transition metal-based catalyst, which is typically palladium on carbon (Pd / C).
[0256] In the process, the hydrogenation step may be carried out in a reactor / autoclave with a hydrogen (H2) pressure of up to 100 bar (such as 80 bar, 60 bar, 40 bar or 20 bar) and a temperature of up to 150°C, preferably up to 100°C, such as, for example, 90°C.
[0257] The catalytic hydrogenation can be carried out in solution using an additional solvent. In this case, the skilled person can select a suitable solvent from a range of standard solvents widely used in organic synthesis according to his / her common knowledge. As examples of typical solvents for the catalytic hydrogenation reaction, mention may be made of, for example, methanol, ethanol, isopropanol, tert-butanol, THF, Me-THF, saturated hydrocarbons or mixtures thereof.
[0258] The reaction can also be carried out without using a solvent. In this case, the catalytic hydrogenation is usually carried out at a temperature at which the substrate is present in molten form.
[0259] The person skilled in the art is able to control the progress of the reaction using standard techniques such as NMR given his / her general knowledge.
[0260] The person skilled in the art, given his / her common general knowledge, is able to purify the product mixture resulting from the hydrogenation step using conventional purification and separation techniques such as distillation, precipitation / crystallization (if applicable) and chromatography (including, for example, flash chromatography and HPLC).
[0261] Catalytic hydrogenation procedures for aromatic aliphatic ketones are described, for example, in US2020 / 0339748A1 (see paragraphs
[0265] -
[0270] of US2020 / 0339748A1), which can be similarly applied to the methods herein. In this preferred embodiment, the reaction is carried out in the absence of any solvent, and a substoichiometric amount of a base (e.g., NaOH) is used as an additive to enhance the hydrogenation selectivity toward the desired benzyl alcohol derivative.
[0262] If necessary, the person skilled in the art will also be able to modify the arylaliphatic ketone hydrogenation procedures known in the art for the purposes of the present invention in view of his / her general knowledge.
[0263] Step c. of alternative a.: The secondary alcohol of formula V: Ar-CH(OH)-CH2-R3(V) (wherein Ar and R3 are as defined above and in the claims) obtainable from step b. is then subjected to a sulfation step with a sulfating agent, which is followed by neutralization with a base XOH or X(OH2), thereby obtaining a compound of formula I, wherein R1 is OSO3X, wherein X is as defined above and in the claims, R2 is H, and R3 is C2--C 26 Aliphatic group.
[0264] The sulfation of secondary alcohols is a standard reaction which forms part of the common general knowledge of the person skilled in the art.
[0265] In the case of this method, the sulfation of the secondary alcohol of formula V: Ar-CH(OH)-CH2-R3(V) can be carried out using known sulfating agents. The sulfating agents that can be used in the present invention are, for example, selected from SO3, chlorosulfonic acid (ClSO3H), oleum and aminosulfonic acid (H3NSO3). Preferably, SO3 or chlorosulfonic acid (ClSO3H) is used as the sulfating agent in the method of the present invention.
[0266] Sulfation can be carried out in solution. Those skilled in the art can select suitable solvent from the range of standard solvents widely used in organic synthesis in view of his / her common knowledge, which includes but is not limited to, for example CH2Cl2, CHCl3, CCl4, pyridine, ethyl acetate, dioxane, diglyme, THF, 2-methyl-THF, hydrocarbons or their mixtures.
[0267] Alternatively, the sulfation can be carried out without any solvent when the alcohol is in its molten state.
[0268] The sulfation step can be carried out at a temperature in the range of -20°C to 120°C, preferably 0°C to 80°C. Due to the exothermic nature of the reaction, the sulfating agent is usually added to the substrate at a relatively low temperature, for example in the range of -20°C to 10°C. The temperature is then usually increased in order to accelerate the reaction and increase the conversion rate. In the case where SO3 is used as the sulfating agent, the sulfation can be carried out using, for example, a so-called falling film reactor, with gaseous SO3 diluted in dry air or dry nitrogen (for example 1% to 5% v / v).
[0269] The person skilled in the art is able, given his / her general knowledge, to monitor the progress of the sulfation reaction using standard techniques such as NMR.
[0270] An aging step may optionally be included after the sulfation step in order to achieve complete conversion to the sulfonic acid.Such an aging step may be carried out, for example, at a temperature between 15°C and 200°C.
[0271] The sulfation step is followed by a neutralization step in order to complete the salt formation of the desired product, ie the compound of formula (I).
[0272] Neutralization can be carried out using a basic compound of the general formula XOH or X(OH)2, wherein X is an alkali metal, alkaline earth metal or ammonium group as defined above. X can be, for example, Li, Na, K, Cs, N-vanadium, triethanolammonium, Mg or Ca.
[0273] Neutralization using a basic compound of the general formula XOH or X(OH)2 is typically carried out in an aqueous solution (or in a solvent mixture to which an aqueous solution of a basic compound of the general formula XOH or X(OH)2 is added). Neutralization is typically carried out at a temperature in the range of 0°C to 100°C, preferably at a temperature in the range of 0°C to room temperature. For the purposes of the present method, "room temperature" is defined herein as being in the range of 20°C to 30°C.
[0274] The person skilled in the art, given his / her common general knowledge, is able to purify the product mixture resulting from the sulfation and subsequent neutralization steps using customary purification and separation techniques, such as distillation, precipitation / crystallization (if applicable) and chromatography (including, for example, flash chromatography and HPLC).
[0275] The person skilled in the art is also able to modify, if necessary, the sulfation procedures applied in the art for the purposes of this method, given his / her general knowledge.
[0276] Alternative b.: Step b. and step c. - Sulfonation - Hydrogenation - Neutralization
[0277] In the following, the sulfonation-hydrogenation sequence of step b. and step c. according to alternative b. of the process will be further described.
[0278] Step b. of alternative b.: In the process according to alternative b., the aromatic aliphatic ketone of formula IV obtained from the decarboxylation cross-ketonization step: Ar-C(=O)-CH2-R3(IV) is sulfonated with a sulfonating agent and subsequently neutralized with a base XOH or X(OH)2 to obtain an aromatic aliphatic ketone sulfonate of formula VI: Ar-C(=O)-CH(SO3X)-R3(VI), wherein Ar, X and R3 are as defined above and in the claims.
[0279] The sulfonation of arylaliphatic ketones using sulfonating agents is known to those skilled in the art and is described, for example, in WO 2018 / 229285A1 (see page 43, lines 5-22). Step b. of alternative b. of the process can be carried out according to the known procedure, as described in WO 2018 / 229285A1.
[0280] According to known procedures from WO 2018 / 229285A1, the sulfonation step in the method can be carried out using, for example, gaseous SO3 as a sulfonating agent, which is preferably diluted in dry air or dry nitrogen (e.g., 1 volume / volume % to 5 volume / volume %). In this case, the sulfonation using diluted SO3 can be carried out using a so-called falling film reactor. Other sulfonating agents that can be used herein include chlorosulfonic acid (ClSO3H), oleum and sulfamic acid (H3NSO3). Preferably, SO3 or chlorosulfonic acid (ClSO3H) is used as a sulfonating agent.
[0281] The reaction is generally carried out at a temperature in the range of -20°C to 200°C, preferably in the range of 0°C to 120°C. Due to the exothermic nature of the reaction, the sulfonating agent is generally added to the substrate at a relatively low temperature, for example in the range of -20°C to 10°C. After the addition is complete, the temperature is generally increased in order to accelerate the reaction and increase the conversion rate.
[0282] Sulfonation can be carried out in solution or in neat solution. A person skilled in the art can select a suitable solvent from the range of standard solvents widely used in organic synthesis in view of his / her common knowledge, including but not limited to, for example CH2Cl2, CHCl3, CCl4, pyridine, ethyl acetate, dioxane, diglyme, THF, 2-methyl-THF, hydrocarbons or mixtures thereof.
[0283] The person skilled in the art is able, given his / her general knowledge, to monitor the progress of the sulfonation reaction using standard techniques such as NMR.
[0284] An aging step may optionally be included after the sulfonation step in order to achieve complete conversion to the sulfonic acid. Such an aging step may be carried out, for example, at a temperature between 15°C and 200°C.
[0285] The sulfonation step is followed by a neutralization step in order to complete the salt formation of the desired product, ie, the arylaliphatic ketone sulfonate of formula VI: Ar-C(=O)-CH(SO3X)-R3(VI).
[0286] Neutralization can be carried out as already described above in connection with step c. of alternative a. of the process according to the invention.
[0287] The person skilled in the art, given his / her general knowledge, is able to purify the product mixture resulting from the sulfonation and subsequent neutralization steps using customary purification and separation techniques such as distillation, precipitation / crystallization (if applicable) and chromatography (including e.g. flash chromatography and HPLC).
[0288] The person skilled in the art will also be able to modify, if necessary, the sulfonation procedures applied in the art for the purposes of the present invention in view of his / her general knowledge.
[0289] Step c. of alternative b.: The arylaliphatic ketone sulfonate of formula VI: Ar-C(=O)-CH(SO3X)-R3(VI) (wherein Ar, X and R3 are as defined above and in the claims) can then be subjected to a hydrogenation step in the presence of H2 and a catalyst to obtain a first compound of formula I, wherein R1 is OH, R2 is SO3X, wherein X is as defined above, R3 is C6-C 16 an aliphatic group; or a second compound of formula I, wherein R1 is H, R2 is SO3X, wherein X is as defined above and in the claims, and R3 is a C6-C16 aliphatic group; or a mixture of the first compound of formula I and the second compound.
[0290] The catalytic hydrogenation of arylaliphatic ketones to give the corresponding arylaliphatic alcohols is a standard reaction known to the person skilled in the art.
[0291] In the case of step c. of alternative b., the catalytic hydrogenation can be carried out analogously as described above for step b. of alternative a. of the process.
