【Abstract】 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.更多还原
