Preparation of dichlorodifluoromethane

Dichlorodifluoromethane is prepared by passing hydrogen fluoride (b.p. 19.4° C) and carbon tetrachloride into a vessel containing antimony trifluoride and a small amount of a SbCl5. Hydrochloric acid and dichlorodifluoromethane are allowed to distil off continuously through a column, the hydrogen fluoride, CCl3F (b.p. 25° C), and carbon tetrachloride being retained.
