The present invention provides adiabatic plug flow 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 comprise one or more designs that minimize the production of by-products at a desired conversion.

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.

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
The multifaceted chemical behavior of polyhalogenated nitrobutadienes, such as 1 and 2, inspired us to test their features in (4+2) cycloadditionreactions. It appears that in the presence of an appropriate diene only the b-chloro-b-nitro vinyl moiety of 1 acts as an efficient dienophile. The resulting cycloaddition products were subsequently converted at the b,b-dichloro position by means of a suitable

Purified chlorinated alkenes are produced by a process in which a mixture of i) a first chlorinated alkene that has at least one beta-chlorine substituent and no alpha-chlorine substituents and ii) a second chlorinated alkene that has at least one alpha-chlorine substituent is contacted with chlorine in an amount sufficient to further chlorinate the second chlorinated alkene, but which is insufficient to cause conversion of more than 20% of the first chlorinated alkene. The resultant reaction product may be easily enriched to provide a chlorinated alkene product wherein a) the weight percentage of chlorinated alkenes having at least one beta-chlorine substituent and no alpha-chlorine substituents, based on the total weight of the chlorinated alkenes present in the enriched chlorinated alkene product compared to b) the weight percentage of chlorinated alkenes having at least one beta-chlorine substituent and no alpha-chlorine substituents, based on the total weight of the chlorinated alkenes present in the mixture prior to chlorination is increased by at least 0.25 wt. %.
