Abstract:
Provided is a method of producing an acid halide solution that is useful in production of a polymerizable liquid-crystal compound. The method of producing an acid halide solution includes: a first step of reacting a specific dicarboxylic acid compound with a halogenating agent in a water-immiscible organic solvent in the presence of at least 1.1 equivalents and not more than 3.0 equivalents of an activator relative to the dicarboxylic acid compound to obtain a reaction liquid including a solution that contains an acid halide compound and an oily liquid that is immiscible with the solution containing the acid halide compound; and a second step of removing the oily liquid from the reaction liquid obtained in the first step to obtain a purified liquid containing the acid halide compound.

Claim (Index 13):
The method of producing a monoester compound according to  claim 12 , wherein\n the weakly acidic buffer solution is an aqueous solution having a pH of at least 5.0 and not higher than 6.0.
