ABSTRACT:
A halogenated hydrocarbon having 1 to 4 carbon atoms is brought into contact with hydrogen fluoride in a gaseous phase in the presence of a catalyst prepared by firing a substance composed mainly of chromium(III) hydroxide in the presence of hydrogen at a temperature of 350.degree. to 500.degree. C. or a catalyst prepared by heat-treating the above substance in an inert gas stream at a temperature of 100.degree. to 600.degree. C. and then firing the heat-treated substance in the presence of hydrogen at the above temperature or any one of catalysts prepared by partially fluorinating the above catalysts.
