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.

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 to selectively produce a monocarboxylic acid ester of a polyvalent alcohol.
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 a first stage in the presence of a first acidic solid catalyst previously swollen with the polyvalent alcohol compound and the product of the first stage is then allowed to react in a second stage in the presence of a second acidic solid catalyst previously swollen with the carboxylic acid compound to selectively produce a polycarboxylic acid ester of a polyvalent alcohol.
