Process for the production of chlorinated propenes

摘要

Processes for the production of chlorinated propenes are provided. The processes proceed through the production of cyclic intermediate that is thereafter readily converted to a desired chloropropane, e.g., via selective pyrolysis. The process may be conducted using starting materials that are readily commercially available and/or that may be reacted safely in standard laboratory equipment so that capital cost savings may be seen. The process does not require the use of catalysts and yet, process conditions less extreme than many conventional processes for the production of chlorinated propenes are suitable, so that raw material and utility cost savings are also possible.

主权项

1. A process for the production of chlorinated propenes, comprising reacting vinylidene chloride with sodium trichloroacetate and/or chloroform, or, reacting perchloroethylene with diazomethane to provide 1,1,2,2,-tetrachlorocyclopropane and converting the 1,1,2,2,-tetrachlorocyclopropane to the desired chlorinated propene.
