Processes for the production of hydrofluoroolefins |
摘要 |
The present invention provides continuous, gas phase, free radical processes for the production of chlorinated and/or fluorinated propenes or higher alkenes from the reaction of chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes, wherein wherein at least a portion of any intermediate boiler by-products generated by the process are removed from the process. |

1. A process for preparing one or more hydrofluoroolefins comprising:
producing one or more chlorinated and/or fluorinated propene/higher alkenes from one or more chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes in a continuous, gas phase, free radical process, wherein at least a portion of any by-products with boiling points between those of two reactants and generated by the process are removed from the process; and converting at least one of the chlorinated and/or fluorinated propene/higher alkenes produced into one or more hydrofluoroolefins. |
