A production method of 1,1,3-trichloro-1-propene comprising the following steps A and B;
Step A: 1,1,1,3-tetrachloropropane is dehydrochlorinated at a temperature between 30° C. and 50° C. in the presence of at least one base selected from the group consisting of alkali metal hydroxides and alkaline earth metal hydroxides, and a phase transfer catalyst,
Step B: 3,3,3-trichloro-1-propene obtained in the step A is isomerized into 1,1,3-trichloro-1-propene in the presence of a metal catalyst.
一种制备1,1,3-三氯-1-丙烯的生产方法,包括以下步骤A和B;步骤A:在至少选择自碱金属氢氧化物和碱土金属氢氧化物组成的群体中的至少一种碱基和相转移催化剂的存在下,在30℃至50℃的温度下脱氯化1,1,1,3-四氯丙烷;步骤B:在金属催化剂的存在下将步骤A中获得的3,3,3-三氯-1-丙烯异构化为1,1,3-三氯-1-丙烯。
