| Abstract: | The esterification of isopropyl acetate was studied and optimized by using A/MCM-41 as catalyst. The activation temperature of catalysts, pace velocity, mole ratio of propylene to acetic acid, the reaction temperature and the pressure of the reaction were all examined and studied, which involved in times in using catalyst and other reaction influences. The optimum conditions of synthesis were determined as follows： activation temperature of catalysts being 180 ℃ activation time being 3 h, the reaction temperature being 160 ℃ the pressure oftbe reaction being 0.tMpa, mole ratio ofpropylene to acetic acid being 4 ： 1, catalyst A（50%）/A/MCM-41 exhibits a stability activity and higher selectivity. |
