| titleOfInvention | Method for Producing Cyclohexanedicarboxylic Acid Monoester |
| abstract | PROBLEM TO BE SOLVED: To provide a method for industrially advantageously producing a cyclohexanedicarboxylic acid monoester compound useful as an intermediate for producing a polymerizable compound for obtaining an optical film, at low cost, in high yield and with high purity. SOLUTION: A step (A) of reacting a 1,4-cyclohexanedicarboxylic acid represented by the following general formula (1) or a derivative thereof with a hydroxy compound represented by the following general formula (2) in an organic solvent. , The step (B) of reducing the water content in the reaction mixture obtained in the step (A) and the reaction mixture obtained in the step (B) are crystallized by adding a poor solvent in which seed crystals are suspended. A method for producing a cyclohexanedicarboxylic acid monoester represented by the following general formula (3), which comprises step (C) [in the formula, R 1 , R 2 and R 3 are as described in the specification. ].
