Production of pentafluoroethane

摘要

A process for the production of pentafluoroethane which comprises the steps (i) producing a composition comprising a compound of formula C2HClxFy in which x=1,2 or 3 and y=2,3 or 4 provided that x+y is 5, contaminated with a compound of formula C2Clx+1Fy, (ii) separating the compound of formula C2HClxFy from the compound of formula C2Clx+1Fy, and (iii) contacting the compound of formula C2HClxFy with hydrogen fluoride in the presence of a fluorination catalyst to produce pentafluoroethane is disclosed.
