Abstract:
The present disclosure provides a method for producing an acid halide solution that is useful as a production intermediate or the like that allows industrially advantageous production of a polymerizable liquid crystal compound. The method for producing an acid halide solution of the present disclosure includes a step α of reacting a halogenating agent and a dicarboxylic acid compound in a water-immiscible organic solvent in the presence of a tetraalkylammonium salt to obtain a water-immiscible organic solvent solution including an acid halide, and a step β of concentrating the obtained water-immiscible organic solvent solution.

Claim (Index 10):
The method for producing a monoester compound of  claim 8 , further comprising a step \u03b4, after the step \u03b3, of washing a reaction solution obtained in the step \u03b3 with a weakly acidic buffer solution.
