[0016] The following describes in detail embodiments for carrying out the present invention (hereinafter simply referred to as "this embodiment"). This embodiment is illustrative for explaining the present invention and is not intended to limit the present invention to the following content. The present invention can be implemented by modifying it as appropriate within the scope of its gist.
[0017] <<Bifunctional Compound>> The bifunctional compound of this embodiment is a compound represented by the following formula (1).
[0018]
[0019] In formula (1), Cy represents a cyclohexyl group, and n represents 0 or 1.
[0020] The bifunctional compound having a norbornane skeleton represented by formula (1) exhibits particularly excellent performance when used as a paint additive, adhesive, resin raw material, etc.
[0021] The bifunctional compound of this embodiment may be produced by carrying out the reaction shown in the following reaction formula. As shown in the following reaction formula, the bifunctional compound of this embodiment can be synthesized using cinnamon alcohol (i.e., 3-phenyl-2-propen-1-ol) as a starting material.
[0022]
[0023] In the above reactions, reaction (1-1) represents the Diels-Alder reaction, reaction (1-2) represents the oxo reaction, and reaction (1-3) represents the reduction reaction (including hydrogenation and nuclear hydrogenation).
[0024] ≪Compounds≫ The compounds of this embodiment may be intermediates in the process of synthesizing the bifunctional compounds of this embodiment. The compounds of this embodiment include the following embodiments.
[0025] <First Embodiment> (Compound of the First Embodiment) The compound of the first embodiment is represented by the following formula (3a) or formula (3b). As shown in these formulas, the compound of the first embodiment is a cyclic olefin compound having a hydroxyl group and a benzene ring.
[0026] The phenyl groups in formulas (3a) and (3b) may each have substituents. Examples of substituents include C1-C4 alkyl groups, C1-C4 alkoxy groups, C1-C4 alkenyl groups, halogens, and hydroxyl groups. The phenyl group may contain 0-5 substituents, for example, 1-3 substituents, or 1 or 2 substituents.
[0027] The compound of the first embodiment is obtained by reaction (1-1), which represents the Diels-Alder reaction in the reaction formula for producing the bifunctional compound of this embodiment described above. This will be explained in more detail below.
[0028] (Method for producing the compound of the first embodiment) The method for producing the compound of the first embodiment includes a cinnamon alcohol reaction step in which cinnamon alcohol and dicyclopentadiene are reacted to obtain the compound of the first embodiment. By including the cinnamon alcohol reaction step in the method for producing the compound of the first embodiment, the compound of the first embodiment can be obtained as an intermediate.
[0029] [Cinnamon Alcohol Reaction Step] The cinnamon alcohol reaction step is a step in which cinnamon alcohol and dicyclopentadiene are reacted to obtain the compound of the first embodiment. The dicyclopentadiene used in the Diels-Alder reaction between cinnamon alcohol and dicyclopentadiene in this embodiment is preferably high-purity dicyclopentadiene. The purity of the dicyclopentadiene is preferably 90% or higher, and more preferably 95% or higher. Furthermore, dicyclopentadiene can depolymerize under heating conditions to become cyclopentadiene (so-called monocyclopentadiene). Therefore, cyclopentadiene may be used instead of dicyclopentadiene.
[0030] In the cinnamon alcohol reaction step, the reaction temperature is preferably 150°C or higher and 300°C or lower. In order to efficiently carry out the Diels-Alder reaction, it is desirable that cyclopentadiene be present in the reaction system. A reaction temperature of 150°C or higher makes it easier for dicyclopentadiene to supply cyclopentadiene, thus making it easier to obtain the compound of the first embodiment. From the above viewpoint, a reaction temperature of 165°C or higher is more preferable. A reaction temperature of 170°C or higher or 175°C or higher is even more preferable. A reaction temperature of 300°C or lower can suppress the formation of high-boiling by-products. From the above viewpoint, a reaction temperature of 250°C or lower is more preferable. A reaction temperature of 220°C or lower or 200°C or lower is even more preferable.
[0031] In the cinnamon alcohol reaction step, the reaction time is preferably 3.0 hours to 10.0 hours, and more preferably 5.0 hours to 8.0 hours.
[0032] Suitable reaction solvents include hydrocarbons, alcohols, and esters. Among these, aliphatic hydrocarbons with six or more carbon atoms, cyclohexane, toluene, xylene, ethylbenzene, mesitylene, propanol, and butanol are preferred.
[0033] The Diels-Alder reaction in this embodiment can be carried out in various ways, including a batch reaction using a tank reactor, a semi-batch reaction in which substrates or substrate solutions are supplied to a tank reactor under reaction conditions, and a continuous flow reaction in which substrates are flowed through a tubular reactor under reaction conditions. The reaction product obtained in the Diels-Alder reaction in this embodiment may be used as is as a raw material for the subsequent hydroformylation reaction, or it may be purified by methods such as distillation, extraction, or crystallization before being used as a raw material for the subsequent hydroformylation reaction.
[0034] In the cinnamon alcohol reaction step, the reaction between cinnamon alcohol and dicyclopentadiene may be carried out in a single step or in multiple steps.
[0035] <Second Embodiment> (Compound of the Second Embodiment) The compound of the second embodiment is represented by the following formula (2a) or formula (2b).

The compounds of the second embodiment are cyclic aldehyde compounds having a hydroxyl group and a benzene ring, as shown in these formulas. The phenyl groups in formulas (2a) and (2b) may each have substituents. Examples of substituents include C1-C4 alkyl groups, C1-C4 alkoxy groups, C1-C4 alkenyl groups, halogens, and hydroxyl groups. The phenyl group may contain 0-5 substituents, for example, 1-3 substituents, or 1 or 2 substituents.
[0038] The compound of the second embodiment is obtained by reaction (1-2) in the reaction formula for producing the bifunctional compound of the above embodiment, which represents an oxo reaction (e.g., a hydroformylation reaction). This will be described in more detail below.
[0039] (Method for Producing Compound of Second Embodiment) The method for producing the compound of the second embodiment includes a hydroformylation step of subjecting the compound of the first embodiment, carbon monoxide, and hydrogen gas to a hydroformylation reaction in the presence of a rhodium compound and an organic phosphorus compound to obtain the compound of the second embodiment. By including the hydroformylation step in the method for producing the compound of the second embodiment, the compound of the second embodiment as an intermediate can be obtained.
[0040] [Hydroformylation Step] The hydroformylation step is a step of subjecting the compound of the first embodiment, carbon monoxide, and hydrogen gas to a hydroformylation reaction in the presence of a rhodium compound and an organic phosphorus compound to obtain the compound of the second embodiment.
[0041] The rhodium compound used in the hydroformylation reaction of the present embodiment is not particularly limited as long as it forms a complex with the organic phosphorus compound and exhibits hydroformylation activity in the presence of carbon monoxide and hydrogen.

[0042] The rhodium compound may be introduced into the reaction mixture together with the organic phosphorus compound to form a rhodium metal hydride carbonyl phosphorus complex having catalytic activity in the reaction vessel, or a rhodium metal hydride carbonyl phosphorus complex may be prepared in advance and introduced into the reactor. Specific examples include, for example, a method in which Rh(acac)(CO) 2 is reacted with an organic phosphorus compound in the presence of a solvent and then introduced into the reactor together with an excess of the organic phosphorus compound to obtain a rhodium-organic phosphorus complex having catalytic activity.

[0044] The hydroformylation reaction in this embodiment can be carried out without a solvent, but a solvent that is inert to the reaction can be used. There are no particular restrictions on the solvent as long as it dissolves each of the above-mentioned components. Specifically, examples include hydrocarbons such as aliphatic hydrocarbons, alicyclic hydrocarbons, and aromatic hydrocarbons; esters such as aliphatic esters, alicyclic esters, and aromatic esters; alcohols such as aliphatic alcohols and alicyclic alcohols; and aromatic halides.

Even more preferably, the reaction temperature in the hydroformylation step is 105°C to 135°C or 110°C to 140°C. When the reaction temperature is 50°C or higher, a sufficient reaction rate can be obtained, and the residue of the compound from the first embodiment, which is the raw material, can be suppressed. Furthermore, by setting the reaction temperature to 170°C or lower, the residue of the compound from the first embodiment, which is the raw material, and the generation of by-products derived from the reaction product can be suppressed.

CO / H 2 By keeping the gas molar ratio within the above range, the reaction activity of the hydroformylation reaction and the selectivity of the target aldehyde are excellent. CO / H introduced into the reaction system 2 As the gas decreases as the reaction progresses, the pre-prepared CO / H 2 In some cases, reaction control can be easily performed by using gas.
[0047] In the hydroformylation step, the pressure is preferably 1.0 MPa to 12.0 MPa, more preferably 1.2 MPa to 9.0 MPa, and even more preferably 1.5 MPa to 5.0 MPa. The pressure in the hydroformylation step is particularly preferably 1.8 MPa to 3.0 MPa. By setting the pressure to 1.0 MPa or higher, a sufficient reaction rate can be obtained, and the residue of the compound of the first embodiment, which is the raw material, can be suppressed. Furthermore, by setting the pressure to 12.0 MPa or lower, the reaction can be easily carried out without using expensive equipment with excellent pressure resistance.
[0048] In this embodiment, batch reactions and semi-batch reactions are preferred as reaction methods for the hydroformylation reaction. In a semi-batch reaction, for example, a rhodium compound, an organophosphorus compound, and the above solvent are added to a reactor, and CO / H 2 This can be carried out by pressurizing and heating with gas to achieve the reaction conditions described above, and then supplying the compound of the first embodiment or its solution, which is the raw material, to the reactor. The reaction product obtained in the hydroformylation reaction of this embodiment can be purified by, for example, distillation, extraction, crystallization, etc.
[0049] In the hydroformylation step, the reaction time is preferably 3.0 hours to 10.0 hours, and more preferably 5.0 hours to 8.0 hours.

R 3 and R 4 are preferably a hydrogen atom or a methyl group, and more preferably a hydrogen atom. In the above formula, i and ii each independently represent an integer of 1 to 3. i and ii are preferably 1 or 2, and more preferably 1.
[0110] In the thermoplastic resin, based on the total number of moles of the structural units, the content of the above-described other structural units is, for example, 1 to 99 mol% or 10 to 80 mol%, preferably 20 to 70 mol% or 25 to 60 mol%, and more preferably 30 to 50 mol% or the like.
[0111] Thermoplastic resins may contain a certain amount of impurities. For example, alcohol compounds such as phenolic compounds that may be produced as by-products during the manufacture of polycarbonate resins, unreacted diol components, or diester carbonates may be present as impurities in thermoplastic resins. However, since alcohol compounds such as phenolic compounds and diester carbonates, which are impurities, can reduce the strength of the thermoplastic resin when it is molded and can cause odor generation, it is preferable to keep their content as low as possible.
[0112] The content of residual phenolic compounds in the thermoplastic resin is preferably 3,000 ppm by mass or less, more preferably 1,000 ppm by mass or less, and particularly preferably 300 ppm by mass or less, based on 100% by mass of the thermoplastic resin. The content of residual diol components is preferably 1,000 ppm by mass or less, more preferably 100 ppm by mass or less, and particularly preferably 10 ppm by mass or less, based on 100% by mass of the thermoplastic resin. The content of residual diester carbonate is preferably 1,000 ppm by mass or less, more preferably 100 ppm by mass or less, and particularly preferably 10 ppm by mass or less, based on 100% by mass of the thermoplastic resin. In particular, it is preferable that the content of compounds such as phenol and t-butylphenol be low, and it is preferable that these compounds be within the above ranges.
[0113] The content of phenolic compounds remaining in thermoplastic resins can be measured by analyzing phenolic compounds extracted from the thermoplastic resin using gas chromatography. Similarly, the content of alcoholic compounds remaining in thermoplastic resins can be measured by analyzing alcoholic compounds extracted from the thermoplastic resin using gas chromatography. The content of diol components and diester carbonates remaining in thermoplastic resins can also be measured by extracting these compounds from the thermoplastic resin and analyzing them using gas chromatography.
[0114] The content of by-product alcohol compounds such as phenolic compounds, diol components, and diester carbonates may be reduced to an undetectable level, but from a productivity standpoint, they may be present in small amounts as long as they do not impair the effect. Furthermore, small amounts can improve plasticity during resin melting.
[0115] The content of each of the remaining phenolic compounds, diol components, or diester carbonates may be, for example, 0.01 ppm or more, 0.1 ppm or more, or 1 ppm or more, based on 100% by mass of the thermoplastic resin. The content of the remaining alcoholic compounds may be, for example, 0.01 ppm or more, 0.1 ppm or more, or 1 ppm or more, based on 100% by mass of the thermoplastic resin.
[0116] The content of by-product alcohol compounds such as phenolic compounds, diol components, and diester carbonates in thermoplastic resins can be adjusted to fall within the above range by appropriately adjusting the polycondensation conditions and equipment settings. It can also be adjusted by the conditions of the extrusion process after polycondensation.
[0117] For example, the residual amount of by-product alcohol compounds, such as phenolic compounds, is related to the type of diester carbonate used in the polymerization of thermoplastic resins, as well as the polymerization reaction temperature and polymerization pressure. By adjusting these factors, the residual amount of by-product alcohol compounds, such as phenolic compounds, can be reduced.
[0118] For example, when thermoplastic resins such as polycarbonate are manufactured using dialkyl carbonates such as diethyl carbonate, the molecular weight does not increase easily, resulting in a low molecular weight thermoplastic resin, and the content of by-product alkyl alcohol compounds tends to increase. Such alkyl alcohols are highly volatile, and if they remain in the thermoplastic resin, the moldability of the resin tends to deteriorate. In addition, if a large amount of by-product alcohol compounds such as phenolic compounds remain, there is a possibility of odor problems during resin molding, and a cleavage reaction of the resin skeleton may proceed during compounding, leading to a decrease in molecular weight. Therefore, it is preferable that the content of residual by-product alcohol compounds in the obtained thermoplastic resin is 3000 ppm by mass or less relative to the thermoplastic resin (100% by mass). The content of residual alcohol compounds is preferably 3000 ppm by mass or less, more preferably 1000 ppm by mass or less, and particularly preferably 300 ppm by mass or less, relative to 100% by mass of the thermoplastic resin.
[0119] ≪Thermoplastic Resin Composition≫ The thermoplastic resin described above may be used as a thermoplastic resin composition containing components other than the thermoplastic resin. The thermoplastic resin composition may contain, for example, at least one additive selected from mold release agents, antioxidants, etc. In the thermoplastic resin composition, the content of secondary components such as additives other than the thermoplastic resin is preferably 20% by weight or less, more preferably 15% by weight or less or 10% by weight or less, even more preferably 7% by weight or less or 5% by weight or less, and particularly preferably 3% by weight or less or 2% by weight or less, based on the total weight. Furthermore, the content of secondary components such as additives other than the thermoplastic resin in the thermoplastic resin composition is, for example, 0.01% by weight or more, preferably 0.1% by weight or more, more preferably 0.5% by weight or more or 1% by weight or more, based on the total weight of the thermoplastic resin composition.

[0129] ≪Methods for Manufacturing Thermoplastic Resins and Thermoplastic Resin Compositions≫ The following describes methods for manufacturing thermoplastic resins and the like. The thermoplastic resins mentioned above can be manufactured by known methods. For example, thermoplastic resins can be manufactured by carrying out a polymerization reaction in a reaction system containing a monomer compound and a catalyst under conditions of a polymerization temperature of 200 to 250°C and a pressure of 760 mmHg to 200 mmHg. For example, a thermoplastic resin such as polycarbonate resin can be manufactured by melt polycondensation using monomer compounds that form the above-mentioned constituent units, such as constituent unit (A), and carbonate precursors such as diester carbonate as raw materials, in the presence of a basic compound catalyst, a transesterification catalyst, or a mixed catalyst containing both, or in the absence of a catalyst.
[0130] Thermoplastic resin compositions can be produced, for example, by melt-kneading one or more types of thermoplastic resins with the aforementioned secondary components, such as additives. Alternatively, they may be produced by dissolving the thermoplastic resins and additives in a solvent, blending them, and then volatilizing the solvent. Suitable solvents include, for example, halogenated organic solvents and THF. Thermoplastic resin compositions can be produced by a manufacturing method that includes such a mixing step. In the mixing step, additives may be mixed with the thermoplastic resins using known methods.

[0139] From the results of GC-MS analysis, NMR analysis, and GC-TOFMS analysis, it was confirmed that each product obtained in Example 1 was the main product, the compound of formula (1a), and the intermediate compounds represented by formulas (1'a), (2a), and (3a), respectively. Furthermore, the final obtained compound of formula (1a) was a mixture of nearly equal amounts of two positional isomers of hydroxyl groups, and it is thought that the ratio of the endo isomer to the exo isomer was approximately 70:30 to 10:90. In the distillation process described above for the compound of formula (1a), it was not easy to reliably separate the endo and exo isomers, which have slightly different boiling points.

Furthermore, based on the results of peak analysis in the GC chart, it is estimated that the ratio of the endo-isomer to the exo-isomer in the compound (3a) above was approximately 30:70.
