  • Processes for the production of hydrofluoroolefins
    Patent number: 8933280
    Abstract: 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.
    Type: Grant
    Filed: October 4, 2013
    Date of Patent: January 13, 2015
    Assignee: Dow Global Technologies LLC

  • Isothermal multitube reactors
    Patent number: 8926918
    Abstract: The present invention provides isothermal multitube reactors suitable for the production of chlorinated and/or fluorinated propene and higher alkenes from the reaction of chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes. The reactors utilize a feed mixture inlet temperature at least 20° C. different from a desired reaction temperature.
