摘要:
Provided is a continuous process for preparing 1,1,2,3-tetrachloro-1-propene having the steps of catalytically dehydrochlorinating CH2ClCCl2CH2Cl in the gas phase to produce CHCl═CClCH2Cl; chlorinating the CHCl═CClCH2Cl to form CHCl2CCl2CH2Cl; and catalytically dehydrochlorinating the CHCl2CCl2CH2Cl in the gas phase to form CCl2═CClCH2Cl.
