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 5):
A mixed solution comprising:\n a water-immiscible organic solvent; a dicarboxylic acid chloride indicated by Formula (III-1) below, where in Formula (III-1), n represents 0 or 1, a tetraalkylammonium salt represented by Formula (I) below,\n R 1 R 2 R 3 R 4 N + A \u2212 \u2003\u2003(I) \n where in Formula (I), A \u2212  represents a halide ion or R 5 SO 3 \u2212 , R 5  represents a methyl group, a phenyl group, or a 4-methyl phenyl group, R 1 , R 2 , R 3 , and R 4  independently represent an alkyl group that is unsubstituted or has a substituent, and a total number of carbon atoms in R 1 , R 2 , R 3 , and R 4  is at least 4 and no greater than 100, and hydrochloric acid in an amount of at least 0.1 parts by mass and no greater than 3 parts by mass with respect to 100 parts by mass of the dicarboxylic acid chloride indicated by Formula (III-1).
