摘要
在生产三氯乙烯和四氯乙烯过程中,会产生大量的低沸点中间产物。研究了从低沸点中间产物中提取反式1,2-二氯乙烯的方法,主要分3个步骤:①对低沸点中间产物进行除酸处理,②工艺流程设计,③对反式1,2-二氯乙烯进行稳定化处理。
In the production of trichloroethylene and tetrachloroethylene,a large amount of low-boiling intermediate products is produced.The method of extracting tra n s-1,2-dichloroethylene from the lowboiling intermediate products was studied.The study comprised mainly 3 steps:①the removal of acid from the low-boiling intermediate,②process design,③the stabilization of trans-1,2-dichloroethylene.
