Abstract:
1. A method for removing a tertiary halogenated hydrocarbon impurity from a target hydrocarbon compound, comprising: providing a first mixture comprising a target hydrocarbon compound and a tertiary halogenated hydrocarbon impurity; feeding the first mixture containing the tertiary halogenated hydrocarbon impurity with into a reactor defining a reaction zone and containing a dehydrohalogenation catalyst effective to catalyze a conversion of the tertiary halogenated hydrocarbon impurity to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon and hydrogen halide, thereby providing a modified mixture; distilling the modified mixture to separate and recover a purified target hydrocarbon compound; and passing a stripping gas stream through the reaction zone.
