The sodium bisulfate and the combination of concentrated sulfuric acid and salicylic acid catalyzed esterification of isoamyl alcohol, isoamyl salicylate were synthesized. Simple and effective are presented. This experiment studied the effects of yield response factors and reuse of the catalyst performance, conclusions: When salicylic acid, isoamyl alcohol and sodium hydrogen sulfate molar ratio of 1 :3:0. 65, 4 drops of concentrated sulfuric acid, refluxing 200 min, ester yield of 84. 1 % is obtained.%用硫酸氢钠与硫酸相结合共同催化水杨酸与异戊醇进行酯化反应;合成了水杨酸异戊酯.方法简单、效果良好.研究了影响产率的反应因素和催化剂的重复使用性能.得出如下结论:当水杨酸、异戊醇和硫酸氢钠的物质的量比为1:3:0.65,硫酸4滴,回流分水200 min,酯收率达84.1％.
