摘要
以十二水合硫酸铁铵为催化剂 ,由乙二醇和乙酸合成了二乙酸乙二醇酯。当乙酸、乙二醇和硫酸铁铵的物质比为5∶2∶0.03 ,甲苯为溶剂 ,回流分水60min ,酯收率可达83.9 %
Ethylene glycol diacetate was synthesized from ethylene glycol and acetic acid with ammonium ferric sulfate dodecahydrate as catalyst.The yield of the ester could reach 83.9% under amount of substance ratio of acetic acid,ethylene glycol and ammonium ferric sulfate were 5∶2∶0.03,toluene as solvent,refluxing and segrating water for 60 min.
