摘要:
Processes for the production of chlorinated propanes and propenes are provided. The present processes comprise catalyzing at least one chlorination step with one or more regios elective catalysts that provide a regioselectivity to one chloropropane of at least 5:1 relative to other chloropropanes.
摘要:
Processes for the production of tetrachloromethane are provided. The present processes involve catalyzing the chlorination of a feedstream comprising partially chlorinated methanes with a free radical initiator. Cost savings are thus provided relative to conventional processes that require the use of high temperatures and/or pressures, and safety concerns are alleviated or eliminated.
摘要:
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.
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.
