摘　　要：通过嫁接的方法合成Al-SBA-15介孔分子筛,以油酸和乙醇为原料,在间歇釜中进行酯化反应实验研究。考察反应温度、原料配比、催化剂用量、反应时间和催化剂硅铝原子比等因素对酯化反应的影响,结果表明,反应温度180℃、催化剂用量为原料质量的1.25%、n(油酸):n(乙醇)=1.0:2.5、反应时间5 h和催化剂硅铝原子比为10时,油酸转化率为83.53%。Mesoporous Al-SBA-15 was synthesized by grafting Al atoms onto siliceous SBA-15 and used as the catalyst for esterification reaction between oleic acid and ethanol in a batchwise reactor.Influence of reaction temperature,n (oleic acid):n (ethanol),catalyst dosage and reaction time was investigated. The optimum condition was obtained as follows:reaction temperature 180℃,n(oleic acid):n(ethanol) = 1.0:2.5,catalyst dosage 1.25%,reaction time 5 h,Si/Al atomic ratio of the catalyst of 10.Oleic acid conversion of 83.53% was obtained under the optimum condition.
