| Zusammenfassung: | The invention relates to a chloropropene refining process. According to the chloropropene refining process, chloride generated in chlorination is fed into a heavy component removal tower, chloropropene and a low-boiling-point mixture are obtained from the tower top, are condensed by virtue of a condenser and a total condenser and are fed to a light component removal tower, and low-boiling-point substances are separated from the tower top; chloropropene is obtained from the tower bottom. Chloropropene prepared by virtue of the chloropropene refining process is relatively high in yield and purity. |
