Title:
METHOD FOR PRODUCING DICARBOXYLIC ACID MONOESTER, DICARBOXYLIC ACID MONOESTER SALT, AND METHOD FOR PRODUCING POLYMERIZABLE LIQUID CRYSTAL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2019/111853
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a dicarboxylic acid monoester with excellent production efficiency, a method for producing a polymerizable liquid crystal compound, and a novel dicarboxylic acid monoester salt. This method for producing a dicarboxylic acid monoester has: a diesterification step for reacting a prescribed dicarboxylic acid compound represented by formula (1) with a prescribed hydroxyl group-containing vinyl compound represented by formula (2) to produce a prescribed dicarboxylic acid diester represented by formula (3); and a monoesterification step for hydrolyzing the dicarboxylic acid diester by means of a base in a solvent containing a secondary or tertiary alcohol to produce a prescribed dicarboxylic acid monoester represented by formula (4).
