| 摘要 |
Processes for the production of chlorinated propenes are provided. The present processes make use of a feedstock comprising 1,2,3-trichloropropane and chlorinates the 1,1,2,3-tetrachloropropane generated by the process prior to a dehydrochlorination step. Production of the less desirable pentachloropropane isomer, 1,1,2,3,3-pentachloropropane, is thus minimized. The present processes provide better reaction yield as compared to conventional processes that require dehydrochlorination of 1,1,2,3-tetrachloropropane prior to chlorinating the same. The present process can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, while limiting the production of waste water, thus providing further time and cost savings. |

1. A process for the production of chlorinated propenes from a feedstream comprising 1,2,3-trichloropropane, comprising at least one chlorination step and at least one dehydrochlorination step, wherein 1,2,2,3-tetrachloropropane produced by the process is recycled and/or further reacted. |
