Production Method For Dicarboxylic Acid Monoester
Abstract: The present invention addresses the problem of providing a production method that is for a polycyclic dicarboxylic acid monoester and comprises collecting a polycyclic dicarboxylic acid existing as an unreacted raw material or impurity, and using the polycyclic dicarboxylic acid in a monoesterification reaction. The production method for a dicarboxylic acid monoester according to the present invention has a monoesterification reaction step for obtaining a dicarboxylic acid monoester from a dicarboxylic acid, wherein the dicarboxylic acid existing as an unreacted raw material is collected and reused in the monoesterification reaction step, or a dicarboxylic acid diester which is a by-product generated as an impurity is hydrolyzed, and the resultant dicarboxylic acid is collected and reused in the monoesterification reaction step.
