The present invention provides improved processes for preparing halogenated alkanes. In particular, the processes comprise reacting an alkene, a halogenated alkene, or combinations thereof and a halogenated methane with at least one chlorine atom.

Processes for preparing halogenated alkanes

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 a weir quench, an apparatus utilizing the weir quench and processes incorporating the same. The weir quench incorporates an inlet having an inner diameter (Di) and an upper chamber having an inner diameter (Duc), wherein the inlet inner diameter (Di) is at least 90% of the upper chamber inner diameter (Duc). The apparatus constitutes a reactor having an outlet with an inner diameter fluidly coupled with the weir quench inlet, wherein the ratio of the reactor oulet inner diameter (Dr) to the weir quench inlet diameter (Di) is greater than one. The weir quench, and apparatus are advantageously utilized in processes utilizing a limiting reagent.

The present invention relates to a process for separating chlorinated methanes utilizing a dividing wall column. Processes and manufacturing assemblies for generating chlorinated methanes are also provided, as are processes for producing products utilizing the chlorinated methanes produced and/or separated utilizing the present process(es) and/or assemblies.

Process for separating chlorinated methanes

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.

Processes for the production of hydrofluoroolefins

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&#xb0; C. different from a desired reaction temperature.
