Date Jan. 29, 1998Method for producing an alkyl carboxylate, in which a carboxylic acid and an alcohol are esterified by reaction in the presence of an acid catalyst, by removing water in a dehydration step established halfway in the esterification reaction using a solid acid catalyst as the acid catalyst, and restarting the esterification reaction to complete the esterification reaction.
