摘要
研究了以冰乙酸和异戊醇为原料 ,采用对甲苯磺酸作催化剂合成乙酸异戊酯。当异戊醇∶冰乙酸∶催化剂的摩尔比为 1 .5∶ 1∶ 0 .0 0 3,不用带水剂 ,在 1 32~ 1 38℃下回流 0 .5h,产率可达96.2 %。
Using ice acetid and isopentys alcohol as raw mate ri al and p-Toluene salpnic acid as catalyst,the method of synthesis of Isopen tyl ethanoate is presented.M (isopestyl alcohol) ∶M (ethanoil acid) (15 ∶1) quanlity of catalyst (0 5 g),reaction temperature (132~138 ℃),time (0 5 h) is the best condition,In this condition the rate of yield in ave rage is 96 2%.
