活性炭固载对甲苯磺酸催化合成乙酸异戊酯

Synthesis of isoamyl acetate catalyzed by p-toluenesulfonic acid supported on activated carbon

研究了用颗粒状活性炭固载对甲苯磺酸作催化剂 ,在优化条件下催化合成乙酸异戊酯。实验结果显示 :催化剂用量为 0 3g,n(醇 )∶n(酸 ) =1 2∶1,用环己烷作带水剂加热 ,在油浴温度为 130～ 135℃下 ,回流 90min时 ,酯化率为 99 5 0 %以上。

It was reported that the synthesis of isoamyl acetate catalyzed by p-toluenesulfonic acid supported on granule activated carbon.The experiment results showed that when amount of catalyst was 0.3 g,molar ratio of alcohol to acid was 1.2:1,reaction time was 90 min,yield of the product was 99.50%.
