The gas-phase hydrofluorination of perchloroethylene into pentafluoroethane (R-125) at T = 330–390°C and P = 0.4 MPa in the presence of a chromium-magnesium catalyst is reported. The reaction rate under these conditions is described by a first-order equation. A hydrofluorination scheme including main product and by-product formation routes is deduced from the observed dependences of particular product selectivities on the total perchloroethylene conversion.
