Abstract: A method for producing a polyvalent alcohol ester compound, characterized in that a polyvalent alcohol compound and a carboxylic acid compound are allowed to react in the presence of an acidic solid catalyst swollen with the polyvalent alcohol compound or the carboxylic acid compound without using a solvent to selectively produce a monocarboxylic acid ester or a polycarboxylic acid ester of a polyvalent alcohol. In this manner, a mono-fatty acid ester and a poly-fatty acid ester (e.g., di-fatty acid ester) of a polyvalent alcohol can be selectively and effectively produced from a polyvalent alcohol compound and a fatty acid compound.
