Technical Field
[0001] Cross - Reference to Related Applications This application claims priority to U.S. Provisional Application No. 63 / 471,611, filed on June 7, 2023. The foregoing application is incorporated herein by reference.
[0002] The present disclosure generally relates to naphthyl glycidyl ether - modified polyether amines obtained from the reaction of naphthyl glycidyl ether and polyoxyalkylene monoamines. Naphthyl glycidyl ether - modified polyether amines can be used for various applications, such as dispersants for soot, asphaltenes, pigments, graphene, and carbon nanotubes, or as deposit control additives in fuel compositions.
Background Art
[0003] During the combustion of fuel, especially gasoline, in an engine, carbonaceous products tend to form carbonaceous particles (soot), which inhibit the performance of the engine. One specific technique that has been used to control soot is to add a deposit control additive to the fuel before combustion. One commonly used type of deposit control additive is polyether amine. Typically, polyether amines are single - molecule additives that have both an amine functional group and a polyether functional group in the same molecule. Prior art polyether amines can be found in Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5, Patent Document 6, Patent Document 7, Patent Document 8, Patent Document 9, Patent Document 10, Patent Document 11, Patent Document 12, Patent Document 13, and Patent Document 14.
[0004] Nevertheless, there is a continuing need to develop new general - purpose polyether amines that can control soot and exhibit effective dispersion performance with respect to other materials such as graphene, asphaltenes, pigments, and carbon nanotubes.

[0006] This disclosure generally provides compositions comprising naphthylglycidyl ether-modified polyetheramines obtained by the reaction of a polyoxyalkylene monoamine with naphthylglycidyl ether. Naphthylglycidyl ether-modified polyetheramines have various applications, for example, It can be used as a dispersant for a variety of materials, including, but not limited to, soot, graphene, asphaltenes, pigments, and carbon nanotubes.
[0007] In another embodiment, naphthylglycidyl ether-modified polyetheramines can be used as deposit control additives and can be added to fuel compositions to form additive-containing fuel compositions.
[0008] In other embodiments, the disclosure provides a deposit control method in an engine and a method for improving engine performance by burning an additive-containing fuel composition in an engine. [Brief explanation of the drawing]
[0009] [Figure 1] A graph showing the relative kinematic viscosity of samples 1-3 is displayed. [Modes for carrying out the invention]
[0010] This disclosure generally relates to compositions comprising naphthylglycidyl ether-modified polyetheramines obtained from the reaction of polyoxyalkyleneamines with naphthylglycidyl ethers. Surprisingly, the naphthylglycidyl ether-modified polyetheramines of this disclosure have been found to be effectively usable as dispersants for soot, as well as for asphaltenes, pigments, graphene, and carbon nanotubes, and as deposit control additives for fuel compositions. For example, because naphthylglycidyl ether-modified polyetheramines have amine groups, they can adhere to functional groups such as carboxylic acid groups present on the soot surface, thereby stabilizing the soot into smaller, dispersible structures and thus reducing the soot's tendency to aggregate. Furthermore, it is known that soot can also contain condensed aromatic ring structures. Therefore, the adhesion force between the naphthylglycidyl ether-modified polyetheramines of this disclosure and soot can be greatly improved because the naphthyl groups can form very strong van der Waals forces with the condensed aromatic ring structures.

[0022] The terms "optional" or "optional" mean that the event or situation described below may or may not occur, and that the description includes both cases in which the event or situation occurs and cases in which it does not occur.
[0023] According to one embodiment, naphthylglycidyl ether-modified polyetheramines can be obtained by the reaction of (a) a polyoxyalkylene monoamine and (b) naphthylglycidyl ether.
[0024] In one embodiment, a polyoxyalkylene monoamine is a compound having one amino group bonded to the end of a polyether skeleton. The amino group can be either a primary (-NH2) amino group or a secondary (-NH-) amino group. In one embodiment, the amino group is a primary amino group. As will be further discussed below, the polyether skeleton is based on, i.e., defined by, alkylene oxide groups, e.g., propylene oxide (PO), ethylene oxide (EO), butylene oxide (BO), and mixtures thereof. In mixed structures, the ratio can be any desired ratio and can be arranged in blocks (e.g., repeating or alternating) or randomly distributed. In one non-limiting example, in a mixed EO / PO structure, the EO:PO ratio can range from about 1:1 to about 1:50, and vice versa. Thus, a polyoxyalkylene monoamine can substantially define polyethylene oxide, polypropylene oxide, and / or polybutylene oxide. The molecular weight of the polyoxyalkylene monoamine is variable and can range up to about 6,000 daltons. According to one embodiment, the molecular weight of the polyoxyalkylene monoamine can be from about 500 daltons to about 6,000 daltons. In another specific embodiment, the polyoxyalkylene monoamine can have a molecular weight from about 600 daltons to about 3,000 daltons.
[0025] Furthermore, in some embodiments in which the naphthylglycidyl ether-modified polyetheramines of this disclosure are prepared for use in highly polar systems such as aqueous media, the polyoxyalkylene monoamine (a) used to form the naphthylglycidyl ether-modified polyetheramine may have a polar group (i.e., polyethylene oxide) in a sufficiently high proportion (e.g., a much larger amount) than the nonpolar group (i.e., polypropylene and / or butylene oxide) for the purpose of achieving a sufficient level of water solubility for a particular area of use. For example, the polyoxyalkylene monoamine may contain more than 50% by weight, or more than 60% by weight, or more than 75% by weight, or more than 90% by weight of ethylene oxide. Similarly, when forming naphthylglycidyl ether-modified polyetheramines for use in nonpolar systems, the polyoxyalkylene monoamine may contain nonpolar groups in a sufficiently higher proportion (e.g., in larger amounts) than polar groups, for example, propylene oxide and / or butylene oxide in amounts exceeding 50% by weight, 60% by weight, 75% by weight, or 90% by weight.
[0026] Polyoxyalkylene monoamines can generally be prepared by reacting a monovalent initiator, such as an alcohol, with ethylene and / or propylene oxide and / or butylene oxide. Following this reaction, the resulting terminal hydroxyl groups are converted to amines, thereby yielding a polyether skeleton comprising propylene oxide (PO), ethylene oxide (EO), butylene oxide (BO), or a mixture thereof, and terminal amino groups, such as a terminal primary amino group or a terminal secondary amino group, preferably a primary amino group. According to one embodiment, the alcohol can be an aliphatic alcohol having 1 to 35 carbon atoms or an aromatic alcohol having 6 to 35 carbon atoms, both of which can be further substituted with alkyl substituents, aryl substituents, arylalkyl substituents, and alkaryl substituents. In another embodiment, the alcohol is The alcohol may be an alkanol having 1 to 18 carbon atoms, or 1 to 10 carbon atoms, such as an alkanol derived from a lower alkyl group, and examples of such alkanols include methanol, ethanol, propanol, butanol, isopropanol, and butanol. In another embodiment, the alcohol may be an alkylphenol in which the alkyl substituent has 1 to 24 carbon atoms, for example, a linear or branched alkyl group of 4 to 16 carbon atoms, or an aryl-substituted phenol including mono, di, and triphenylphenol, or an arylalkylphenol, such as tristyryl(stryl)phenol, or naphthol, or an alkyl-substituted naphthol.
[0027] According to one particular embodiment, a polyoxyalkylene monoamine is a compound having the following general formula: [ka] In the formula, R is C1-C 40 Alkyl alkyl group or C1-C 40 It is an alkylphenol group; each R' is independently hydrogen, methyl, or ethyl; and n is an integer from about 1 to about 50. Specific examples include, but are not limited to, compounds having the following formulas: [ka] [ka] [ka] and CH3-[OCH2CH2] a -[OCH2CH(CH3)] b -NH2 In the formula, Me is methyl, Et is ethyl; f is an integer from about 13 to about 14; e is an integer from about 2 to about 3; a is an integer from 1 to about 45; and b is an integer from 1 to about 30. In some embodiments, the a / b ratio can be in the range of about 1 / 9 to about 4 1 / 4, for example, about 1 / 9, or about 6 / 29, or about 19 / 3, or about 3 3 / 10, or about 4 1 / 4. Examples of such polyoxyalkylene monoamines included in the above formula include JEFFAMINE® M-600, M-1000, M-2005, M-2070, FL-1000, C-100; XTJ-435; XTJ-436 amines, and SURFONAMINE® B-60, B-100, L-100, L-200, and L-207 amines.

[0029] Naphthylglycidyl ether-modified polyetheramines can be reacted by contacting naphthylglycidyl ether with a polyoxyalkylene monoamine at a temperature of approximately 50°C to 300°C. For example, the reaction can occur at temperatures in the range of approximately 150°C to 200°C. The reaction can also occur under pressures in the range of approximately 1 to 2000 psi. The reaction time can vary from approximately 30 minutes to approximately 6 hours. Methods for removing water by condensation can also be employed. In some embodiments, naphthylglycidyl ether and polyoxyalkylene monoamine can be reacted in a molar ratio (naphthylglycidyl ether:polyoxyalkylene monoamine) of approximately 0.9:1.1 to approximately 1.1:0.9, or approximately 0.95:1.05 to approximately 1.05:0.95, or approximately 1:1.

In some embodiments, the composition contains at least 50% by weight of the mono-adduct compound, where the weight percentage is based on the total weight of the mono-adduct compound and the di-adduct compound. In yet another embodiment, the composition contains at least 60% by weight, or at least 70% by weight, or at least 80% by weight, or at least 90% by weight, or at least 95% by weight of the mono-adduct compound, where the weight percentage is based on the total weight of the composition.

That is, in one embodiment, an aqueous or non-aqueous composition is provided containing the naphthylglycidyl ether-modified polyetheramine of the present disclosure, water and / or other solvents, and optionally one or more of the auxiliary agents described below. The amount of water and / or solvent present can be, for example, about 0.5% by weight to about 50% by weight, based on the total weight of the aqueous or non-aqueous composition. Thus, the amount of naphthylglycidyl ether-modified polyetheramine (and optional auxiliary agents) contained in the aqueous or non-aqueous composition can range from about 50% by weight to a maximum of about 99.5% by weight, based on the total weight of the aqueous or non-aqueous composition.

The fuel additive concentrate may generally contain the composition containing naphthylglycidyl ether-modified polyetheramine in amounts of about 0.001% to about 99% by weight, or about 0.5% to about 80% by weight, or about 0.75% to about 70% by weight, or about 1% to about 60% by weight, or about 5% to about 50% by weight, or about 10% to about 40% by weight, based on the total weight of the fuel additive concentrate.
[0049] Additional performance-enhancing additives include, but are not limited to, antioxidants (e.g., in amounts of about 8-100 mg / kg of the fuel additive concentrate), such as hindered phenols or their derivatives and / or diarylamines or their derivatives; corrosion inhibitors (e.g., in amounts of about 5-100 mg / kg of the fuel additive concentrate); and / or detergent / dispersant additives, such as further polyetheramine or nitrogen-containing detergents, including, but not limited to, PIB amine detergents / dispersants, succinimide detergents / dispersants, and other quaternary salt detergents / dispersants containing quaternary ammonium imide salts (which are detergents having an imide group and a quaternary ammonium salt).
[0050] Other additional performance-enhancing additives include: low-temperature fluidity enhancers, such as maleic anhydride and styrene ester copolymers and / or ethylene and vinyl acetate. Nyl copolymers, etc.; antifoaming agents and / or defoaming agents, e.g., silicone oil, etc.; deemulsifiers, e.g., polyalkoxylated alcohols, etc.; lubricants, e.g., fatty carboxylic acids, etc.; metal deactivators, e.g., aromatic triazoles or their derivatives, including, but not limited to, benzotriazoles; and / or valve seat recession additives, e.g., alkali metal sulfosuccinates, etc.
[0051] Additional performance-enhancing additives may include: biocides; antistatic agents, de-icing agents, fluidizers, such as mineral oil and / or poly(alpha-olefin) and / or polyethers; and combustion aids (for example, in amounts of about 8 to 150 mg / kg of fuel additive concentrate), such as octane or cetane improvers.
[0052] The total amount of additional performance-enhancing additives present in the fuel additive concentrate can be less than about 50% by weight, less than about 20% by weight, less than about 10% by weight, or less than about 1% by weight, based on the total weight of the fuel additive concentrate. In other embodiments, the total amount of additional performance-enhancing additives present in the fuel additive concentrate can be at least about 0.001% by weight, at least about 0.5% by weight, at least about 2.5% by weight, at least about 5% by weight, or at least 15% by weight, based on the total weight of the fuel additive concentrate. In yet another embodiment, the total amount of additional performance-enhancing additives present in the fuel additive concentrate can be about 0.001 to 60% by weight, about 0.1 to 50% by weight, or about 1 to 40% by weight, based on the total weight of the fuel additive concentrate.
[0053] Additional performance-enhancing additives can each be added directly to the fuel additive concentrate and / or fuel composition, but generally, they are mixed with a composition containing naphthylglycidyl ether-modified polyetheramine to form a fuel additive concentrate, which is then mixed with fuel to form a fuel composition.
[0054] Fuel additive concentrates may also include carrier oils, such as inorganic carrier oils or synthetic carrier oils. Suitable inorganic carrier oils include fractions obtained from crude oil processing, such as bright stock or base oils with a viscosity of, for example, SN500 to 2000, as well as aromatic hydrocarbons, paraffinic hydrocarbons, and alkoxy alkanols. Equally useful are fractions obtained from the refining of mineral oils, known as "hydrocracking oils" (obtained by vacuum distillation cuts with a boiling point range of approximately 360°C to 500°C, or by hydrogenating and isomerizing natural mineral oils under high pressure using a catalyst, and deparaffinizing them). Equally suitable are mixtures of the above inorganic carrier oils. Examples of suitable synthetic carrier oils include polyolefins (polyalphaolefins or polyinternal olefins), (poly)esters, (poly)alkoxylates, polyethers, polyethers starting from alkylphenols, and carboxylic acid esters of long-chain alkanols.
[0055] In some embodiments, the carrier oil may be present in the fuel additive concentrate in an amount of about 0.5% to about 50% by weight, or about 2% to about 40% by weight, or about 3% to about 30% by weight, based on the total weight of the fuel additive concentrate.
[0056] The fuel additive concentrate may also contain a solvent. The solvent provides a homogeneous fuel additive concentrate and facilitates the transfer and handling of the fuel additive concentrate. In some embodiments, the solvent is an aliphatic hydrocarbon, an aromatic hydrocarbon, or a mixture thereof.
[0057] Examples of aliphatic hydrocarbons include various naphtha and kerosene boiling fractions that are mostly aliphatic. Examples of aromatic hydrocarbons include benzene, toluene, xylene, and various naphtha and kerosene boiling fractions that are mostly aromatic. In one embodiment, the solvent is in the fuel additive concentrate, based on the total weight of the fuel additive concentrate, at about 1 by weight. It can be present in amounts of approximately 90% by weight, in another embodiment, approximately 25% by weight to approximately 85% by weight, and in yet another embodiment, approximately 40% by weight to approximately 80% by weight.
[0058] Compositions containing naphthylglycidyl ether-modified polyetheramines can be added to fuel at any convenient point in the supply chain, either alone or as part of a fuel additive concentrate. For example, a composition or fuel additive concentrate containing naphthylglycidyl ether-modified polyetheramines can be added at a refinery, at a logistics terminal, or after the fuel has left the logistics terminal. When added to fuel after it has left the logistics terminal, this is called an aftermarket application. Examples of aftermarket applications include adding a composition or fuel additive concentrate containing naphthylglycidyl ether-modified polyetheramines to fuel in a delivery tanker, directly to a customer's large storage tank, or directly to the vehicle tank of the end consumer. Another example of an aftermarket application is supplying a composition or fuel additive concentrate containing naphthylglycidyl ether-modified polyetheramines in small bottles suitable for direct addition to storage tanks or vehicle tanks.

[0065] Example 3 - Dispersion Test Results
[0066] Using the polyetheramine and Surfonamine® B-100 from Example 1, carbon black was dispersed in paraffin oil. The kinematic viscosity of the dispersion system at 40°C was measured using a Brookfield viscometer. Lower viscosity indicates better dispersion effect of the dispersant. The dispersion system of Example 3 is shown in Table 1A below.
[0067] [Table 1]
[0068] Samples 1-3 were thoroughly stirred on a vibrator to ensure even dispersion. The kinematic viscosity of each sample (1-3) was measured as described above. The results are shown in Table 1 and Figure below. [Table 2]
[0069] As shown in the figure, the polyetheramine in Example 1 results in improved dispersion of carbon black.
