摘　　要：利用对甲苯磺酸为催化剂 ,由乙二醇和乙酸合成了二乙酸乙二醇酯 ,当 0 .2mol乙二醇 ,0 .5mol乙酸 ,15ml苯和 1.0g催化剂一起加热回流分水 1.5小时 ,酯收率达 94 .9%。Ethylene glycol diacetate was synthesized from ethylene glycol and aectic acid by using p-toluene salphonic acid as catalyst. That a mixture of 0.2mol ethylene glycol, 0.5mol acetic acid, 15ml benzene and 1.0g catalyst was heated for 1.5 hour at reflaxing temperature, the yield of the ester was 94.9%.
