摘要
以异戊醇和冰乙酸为原料,采用硫酸铝(Al_2(SO_4)_3·18H_2O)作催化剂合成醋酸异戊酯.考察了催化剂用量、原料配比和反应时间等因素对反应的影响.确定了硫酸铝作为催化剂的最佳反应条件:n_(冰乙酸):n_(异戊醇)=1:0.6(摩尔比),硫酸铝用量为0.5 g,反应时间1.5 h,产品收率(以0.2mol冰乙酸计)达95.2%.并且对催对剂的重复使用效果作了讨论.
Iso-Amyl acetate was preprared by isoamyl alcohol and glacial acetic acid with aluminum sufate crystal as catalyst. The optimum conditions are as follows:1:0.6;mass of catalyst, 0. 50 g,reaction time,l. 5 h,Yield of iso-pentyl acetate is 95. 2%(based on 0. 2 mol glacial acetic acid). The reuse of catalyst is investigated.
