Abstract
A method for producing an ester comprising the steps of reacting an alcohol with a carboxylic acid to obtain a crude esterfied product, adding 5 to 100 parts by weight of a hydrocarbon solvent with respect to 100 parts by weight of the crude esterified product and performing neutralization with an alkali aqueous solution. An alcohol solvent can be added, if necessary. Thus, a method for producing an ester is provided in which a high-quality ester is obtained at a high yield.
