摘　　要：以Waugh结构(NH_4)_6[MnMo_9O_(32)]8H_2O作为催化剂,应用控制变量法确定最佳反应条件,合成丙酸丁酯.经实验确定的最佳反应条件为:醇酸摩尔比为1.6:1.0,催化剂用量为0.2g,反应时间为2.5h,带水剂为甲苯,带水剂用量为2m L,转化率达到99.30%.Synthesis of butyl propionate Catalyzed by（ NH4）6[Mn Mo9O（32）]8H2O with Waugh Structure. And application control variable method for determining the optimal reaction conditions. After determining the optimal reaction conditions for the experiment,acid and alcohol molar ratio of 1. 6： 1,the amount of catalyst 0. 2g,reaction time 2. 5h,with agent dosage 2ml,the conversion rate of 99. 30%. After the butyl propionate was distilled off,sodium carbonate,sodium chloride,calcium chloride treatment and distillation. Once again,the collected substance was distilled off,and the refractive index for infrared detection,Butyl propionate product was determined.
