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 1):
A method of producing an acid halide solution comprising:\n a first step of reacting a dicarboxylic acid compound of formula (I), shown below, where n is 0 or 1, 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 of formula (I) to obtain a reaction liquid including a solution that contains an acid halide compound of formula (II), shown below, where n is 0 or 1 and X is a halogen atom, and an oily liquid that is immiscible with the solution; and\n 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 of formula (II).
