Abstract

1-Bromo- 1-chloro- 2,2,2-trifluoroethane is prepared by heating 1,2-dibromo-1-chloro-2,2-difluoroethane with substantially anhydrous hydrogen fluoride in the presence of an antimony fluorochloride catalyst, at least part of the antimony being in the pentavalent state. The preferred temperature range is p 70-160 DEG C. Specifications 767,779 and 805,764 are referred to.
