摘　　要：用交联聚苯乙烯 -异氰尿酸树脂催化乳酸与正丁醇的酯化反应 ,发现虽然该树脂的酸性与羧酸相近 ,但能有效地催化酯化反应 。The esterification of lactic acid with n-butanol, catalyzed by the polystyrene-isocyanuric acid resins was studied, and it was discovered that though the acidity of the resins was close to that of carboxylic acid, the resins could catalyze the esterification reaction efficiently. Thus the mechanism of hydrogen bond assisting catalysis was suggested.
