SELECTIVE DEHYDROHALOGENATION OF TERTIARY HALOGENATED HYDROCARBONS AND REMOVAL OF TERTIARY HALOGENATED HYDROCARBON IMPURITIES
摘要
A method for removing a tertiary halogenated hydrocarbon impurity from a target hydrocarbon compound, comprising: providing a first mixture comprising the target hydrocarbon compound and a tertiary halogenated hydrocarbon impurity; contacting the first mixture containing the tertiary halogenated hydrocarbon impurity with 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, the dehydrohalogenation catalyst comprising a sorbent that includes silicon oxide, aluminum oxide or both silicon oxide and aluminum oxide; and distilling the modified mixture to separate and recover a purified target hydrocarbon compound.
