采用分子筛— 4 A负载了 Sn Cl4 · 5 H2 O,制备出复合催化剂 ,并研究了它对合成丁酸异戊酯的催化性能和最佳合成条件是 :醇酸摩尔比为 1.2 ,带水剂甲苯为 15 m l,催化剂用量为 2 .5 g,反应时间为 4 0 min,酯收率达 96 .2 % The molecular sieve-4 A was loaded with Sn Cl4 · 5H 2 O to prepare a composite catalyst. The catalytic performance of the isopentyl butyrate and its optimum synthesis conditions were studied. The optimum conditions for the synthesis of isoamyl butyrate were as follows: Toluene 15 ml, the amount of catalyst was 2.5 g, the reaction time was 40 min, the ester yield was 96.2%
