PCT No. PCT/JP92/01350 Sec. 371 Date Jun. 15, 1993 Sec. 102(e) Date Jun. 15, 1993 PCT Filed Oct. 16, 1992 PCT Pub. No. WO93/08152 PCT Pub. Date Apr. 29, 1993.The present invention provides a process for producing a halomethyl ester of an aliphatic carboxylic acid in which a metal salt of an aliphatic carboxylic acid is reacted with a dihalomethane in the presence of a phase transfer catalyst, whereby the efficient production of a halomethyl ester of an aliphatic carboxylic acid has been made possible without the formation of a halomethyl ether as a by-product. The bis compound bis[aliphatic carbonyloxy)methane], which is obtained as a by-product, is hydrolyzed to enable the quantitative recovery of an aliphatic carboxylic acid and its reuse. Thus, the present process is preferable as a process for industrial production of a halomethyl ester of an aliphatic carboxylic acid.
