Title:
METHOD FOR PRODUCING ACID HALIDE SOLUTION AND METHOD FOR PRODUCING MONOESTER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/130871
Kind Code:
A1
Abstract:
The present invention provides a method for producing an acid halide solution that is useful when producing a polymerizable liquid crystal compound. This method for producing an acid halide solution includes: a first step of obtaining a reaction solution comprising a solution that contains an acid halide compound which is obtained by reacting a specific dicarboxylic acid compound with a halogenating agent in a water-immiscible organic solvent in the presence of an activator at a quantity of 1.1-3.0 equivalents relative to the dicarboxylic acid compound, and that contains an oily liquid which is immiscible with the solution containing the acid halide compound; and a second step of removing the oily liquid from the reaction solution obtained in the first step so as to obtain a purified solution that contains the acid halide compound.
