合成乙基氯化物的工艺改进

Improvement on Synthesis of Ethyl Chloride.

以五硫化二磷为原材料 ,在吡啶催化下 ,同无水乙醇反应合成乙基硫化物 ,再与氯气反应 ,经亚硫酸氢铵和碳酸铵精制 ,得到高纯度的乙基氯化物 ,总收率达到 87

Ethyl Chloride can be obtained from Phosphorous Pentasulfide, anhydrous alcohol, and pyridine as catalyst, then reacted with Chlorine gas, refined with Ammonium Hydrogen Sulfite and Ammonium Carbonate, the captioned product of higher purity will be prepared with yield over 87.6%.
