四氯丙烯合成路线
四氯丙烯制备
其制备方法是以1，3-二氯丙烯为原料，经二次氯化、二次脱氯化氢和异构化而制得。一次氯化：在具有外循环管道的氯化反应器内加入1，3-二氯丙烯，在光照条件下维持一定的反应温度，通氯气至反应器底部进行氯化反应，达到终点后停止通氯气，通入氮气除去多余的氯气，得到氯化液移人到蒸馏釜，加入少量的阻聚剂进行减压蒸馏，得1，2-二氯丙烷和中间馏分，收集105～110℃/13.330 kPa馏分为1，1，2，3-四氯丙烷。
一次脱氯化氢：在装有搅拌的反应器中投入1，1，2，3-四氯丙烷、氢氧化钙和一定量的水，在一定温度下反应数小时，加入1∶1的盐酸中和至酸性，沉降分层收集混位三氯丙烯。
二次氯化：反应设备操作同一次氯化，投入混位三氯丙烯，得混位五氯丙烷。
二次脱氯化氢：生产设备操作同一次脱氯化氢，在反应釜投入混位五氯丙烷，加入氢氧化钙，脱氯化氢得四氯丙烯。
异构化：在装有搅拌器的反应釜中投入混位四氯丙烯及少量的异构化催化剂，在一定温度下反应数小时，完成异构化反应，减压蒸馏，收集102～104℃/13.33 kPa馏分即1，1，2，3-四氯丙烯。
ClCH=CHCH2Cl+Cl2→ClCH2CHClCHCl2
ClCH2CHClCHCl2+OH-→ClCH2ClG=CHCl
ClCH2ClC=CHCl+Cl2→Cl2CHCCl2CH2Cl
Cl2CHCCl2CH2Cl+OH-→Cl2C=CClCH2Cl
