Abstract
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.
