Three-tower continuous distillation process of ethyl acetate from aldehyde condensation and purification by gas-phase oxidation of aceticacid and ethylene were also discussed.
Ethylene glycol diacetate was synthesized from ethylene glycol and aceticacid with ferric chloride hydrate as catalyst. The yield of ester was 92% under the optimum condition.
利用氯化铁水合物为催化剂,从乙二醇和冰醋酸制备了二乙酸乙二醇酯,在最佳条件下其收率达92%。
