Abstract
The invention relates to the manufacture of chlorofluoroethanes of formula CF.sub.3 --CHF.sub.x Cl.sub.2-x, where x is equal to 0 or 1, by catalytic hydrogenation of a perhaloethane of formula CF.sub.3 --CF.sub.x Cl.sub.3-x. The use of an iridium-based catalyst deposited on a support enables the selectivity to be improved.
