Abstract
It is an object of this invention to provide a method for producing an ester by a transesterification reaction in which the reaction can be stably performed in a short time at a pressure approximately equal to normal pressure. The ester is produced by a transesterification reaction in which a starting material ester and an alcohol are brought into contact with a solid acid catalyst that displays the characteristics of a very strong acid in terms of the absolute value of argon adsorption heat ranging from 15 to 22 kJ/mol. In particular, it is preferable that the starting material ester in a liquid phase and alcohol in a vapor phase be brought into contact with the solid acid catalyst, and that the starting material ester be oil or fat, and the alcohol be methanol or ethanol.
