氯甲酸-β-氯乙酯的合成

Synthesis of β-chloroethyl chlorocarbonate

报道了氯甲酸 β 氯乙酯的两种合成方法,并对光气法进行了研究。其最佳反应条件为:温度为30℃,反应时间为2～2.5h,氯乙醇与光气摩尔比为1∶3。在上述条件下,氯甲酸 β 氯乙酯收率可达88.3%。

Two methods of synthesis of β-chloroethyl chlorocarbonate are reported, and the synthesis method of β-chloroethyl chlorocarbonate with phosgene is studied.The optimum reaction conditions are that the reaction temperature is 30℃, the reaction time is 2～2.5 h,and the mole ratio of chloroethanol to phosgene is 1∶3 。 Under above conditions,the yield of β-chloroethyl chlorocarbonate reached 88.3%.
