摘要: 在金属铁源催化剂和磷酸酯促进剂的存在下，以乙烯与四氯化碳为原料的催化反应制备1,1',1'',3-四氯丙烷，再以1,1',1'',3-四氯丙烷为中间体原料来设计合成1,1',2,3-四氯丙烯的终端产品，结果表明，以1,1',1'',3-四氯丙烷为原料合成1,1',2,3-四氯丙烯工艺步骤简单，对设备要求相对较低，适合国内发展行情，该产品对工业化生产具有很大的发展潜力。

Abstract: In the presences of metal iron catalyst source and phosphate promoter, 1,1',1'',3-tetracloropropane was prepared by the reaction of ethylene and carbon tetrachloride as starting materials. Then, 1,1',1'',3-tetracloropropane was designed and synthesized from 1,1',1',3-tetracloropropane as an important intermediate. The results showed that: the synthesis process of 1,1',2,3-tetraclo ropropylene from 1,1',1'',3-tetracloropropane is simple, may be obtained with high yield and relatively low requirements for equipments. It is suitable for domestic development and has great development potential for industrial production.
