摘　　要：制备了活性炭固载对甲苯磺酸催化剂,以乙酸和正己醇为原料合成了乙酸正己酯,考察了影响酯化率的各种因素,确定了最佳反应条件为:乙酸用量为0.1 mol时,醇酸物质的量比为1.4,催化剂用量为3 g,15 mL甲苯作带水剂,反应时间30 min,酯化率达94%以上.Hexyl acetate was synthesized from acetic acid and n - hexanol with c - toluenesulfonic supported on activated carton as catalyst. The effect of factors on esterification ratio was studied. The result shows that the best reaction condition was： based of 0.10mol acetic acid, molar ratio of n - hexanol to acetic acid was 1.4, mass of catalyst was 3g, the taking water reagent was 15mL, reaction time was 30min. The yield of the product could reach over 94%.
