摘要
将Waugh结构(NH_4)_6[MnMo_9O_(32)]·8H_2O(HPC)负载于硅胶上,探究其催化合成乙酸异戊酯的条件.通过单因素试验确定最佳反应条件为:醇酸比为1.6∶1,带水剂为甲苯,催化剂用量为0.4g,反应时间为60min左右,最终转化率达85.4%.
The condition of synthesis of isoamyl acetate catalyzed by(NH_4)_6[MnMo_9O_(32)]·8H_2O(HPC)with Waugh structure load on silicon was studied.The results indicated that the optimized conditions of the reaction were as follows:the molar ratio of the alcohol to acid was 1.6∶1,the amount of the catalyst was 0.4 g,with toluene as water-carrying agent,the reaction time was 60 min,and the conversation rate was up to 85.4%.
