Abstract
The invention relates to the preparation of pentafluoroethane (F125) by catalytic hydrogenation in the vapour phase of chloropentafluoroethane (F115). The use of a palladium-based catalyst deposited on a support of alumina, of fluorinated alumina or of aluminium fluoride, makes it possible to obtain excellent selectivities in F125 and to avoid the formation of 1,1,1-trifluoroethane (F143a).
