摘要
The present invention relates to a polyhydric alcohol / fatty acid esterification heterogeneous catalyst and a method of applying the same, and more particularly, when the ester reaction of a polyhydric alcohol and a fatty acid is carried out under a catalyst, a specific catalyst activator, a catalytic activity enhancer, and an inorganic support are used as the catalyst. By using a heterogeneous catalyst, the acid value and the hydroxyl value are much lower than those of the conventional homogeneous catalyst system, and at the same time, the deoxidation and washing processes for removing unreacted fatty acids and catalysts are omitted, and thus economical and environmentally friendly polyhydric alcohols / It relates to a fatty acid esterification heterogeneous catalyst and a method of applying the same.;Polyhydric alcohols, fatty acids, esterification reactions, heterogeneous catalysts
