摘　　要：对标题化合物的合成进行了研究。以粗品乙基硫化物为原料,通过对粗品乙基硫化物蒸馏提纯,再与氯气在物质的量比约为1∶1下反应,所得粗品氯化物采用蒸馏加水洗方法精制,大大减少了废水量,得到纯度≥99%的乙基氯化物,且最后所得硫磺松散性好、纯度高。The crude O, O-diethyl-phosphorochloridothionates was obtained via distillation, chlori nation using crude O, O- diethyl-thionothiolphosphoric acids as the starting material. Then O,O-di ethyl-phosphorochloridothiouates was refined through distillation and washing with water. The target product with high purity of 99% was prepared via this process. The wastewater was cut down largely and the by-product was comprehensive utilized to form high quality sulfur.

关 键 词：乙基氯化物 蒸馏 废水量
