Conventionally, as a method for producing an alicyclic diol represented by the above formula, an unsaturated alicyclic diol obtained by a Diels-Alder reaction between an excess amount of cyclopentadiene or dicyclopentadiene and fumaric acid diethyl ester has been used. A method has been known in which diethyl ester is used as a raw material and the hydrogenation reaction is carried out twice. That is, in the conventional method, the unsaturated alicyclic diethyl ester is first hydrogenated at about 100°C in the presence of a palladium-based catalyst in a solvent such as benzene, and the olefinic double bond is reduced in advance. After forming the cyclic diethyl ester □, in the presence of an Adkins type copper chromite catalyst in a solvent such as dioxane, 20
It was necessary to perform a two-step hydrogenation reaction in which the ethyl ester group was reduced to a hydroxymethyl group by hydrogenation reaction at about 0°C. This is because the hydrogenation reaction using an Adkins-type copper chromite catalyst requires a high temperature, and if the hydrogenation reaction is performed at -degrees, the Diels-Alder reaction is an equilibrium reaction. This is because it was thought that the ester would decompose (

However, in the above method, in addition to having two hydrogenation reaction steps, it is difficult to transfer the alicyclic diethyl ester obtained in the first step hydrogenation reaction to the second step hydrogenation reaction. Usually, multiple operations such as catalyst filtration and vacuum distillation are required, which is complicated in production. Therefore, in order to produce the target alicyclic diol represented by the above formula, It took a very long time and a lot of manufacturing cost.

The reaction conditions for producing the unsaturated alicyclic dialkyl ester represented by the above-mentioned formula (I) or (Ill) are not particularly limited, and conventionally known methods may be adopted, but the preparation of the starting materials It is preferable that less than 1 mol part of dicyclopentadiene be reacted with 1 mol part of fumaric acid dialkyl ester and/or maleic acid dialkyl ester. If the amount of dicyclopentadiene is 1 mole part or more, by-products such as addition polymers of cyclopentadiene will increase, and the unsaturated product represented by general formula (1) or (I[]), which is the target product, will increase. This is not preferred because the selectivity, yield, and purity of the alicyclic dialkyl ester decrease. That is, when a rectification operation is performed to increase the purity of the target unsaturated alicyclic dialkyl ester represented by the general formula (1) or (In) from the reaction mixture, the low thermal stability of the compound Since thermal decomposition occurs due to the chemical properties, ordinary simple distillation operations are simply employed, and it becomes difficult to achieve high purity of the compound. On the other hand, after hydrogenating the unsaturated alicyclic dialkyl ester, it takes a lot of effort to remove a large amount of byproducts from the reaction system, and furthermore, the purity of the compound is low, so hydrogenation is not an option. There are disadvantages such as a decrease in reaction rate, so it is important to sufficiently suppress by-products during the Diluce-Alder reaction.

Furthermore, the method for producing the unsaturated alicyclic dialkyl ester represented by the above-mentioned formula (III) is not limited to the above-mentioned method, and for example, the unsaturated alicyclic dialkyl ester represented by the above-mentioned formula (I) A method in which a dialkyl ester of the formula is reacted with dicyclopentadiene may also be used. Even when using this method, the amount of dicyclopentadiene used is determined to minimize by-products such as addition polymers of cyclopentadiene.
- The total amount of dicyclopentadiene used is 1 mole part of fumaric acid dialkyl ester and/or maleic acid dialkyl ester used to synthesize the unsaturated alicyclic dialkyl ester represented by formula (1). It is preferable that the amount is less than molar parts. In addition, the unsaturated alicyclic dialkyl ester represented by the formula (1) may be a reaction recovery product when synthesizing the unsaturated alicyclic dialkyl ester represented by the general formula (m), or It may contain unreacted dicyclopentadiene.

65 g of residue is 325 g of N,N-dimethylformamide.
After heating and dissolving the solution in ml, it was left to stand at 5°C for 72 hours, and the crystals of the cyclopentadiene polymer were filtered off. Next, N,N-dimethylformamide was removed from the filtrate by vacuum distillation, and then recrystallized twice with 220 ml and 100 ml of ethanol to obtain a 3:1 adduct with n=2. 22 g of R-methyl group (purity of 3:1 adduct by gas chromatography: 98% by weight) was obtained.
