摘要：
An improved gas-phase process for the manufacture of 1,1,1-trifluorodichloroethane and/or 1,1,1,2-tetrafluorochloroethane by contacting a suitable tetrahaloethylene with hydrogen fluoride in the presence of a selected metal in combination with a high fluorine content aluminum-containing compound, the reaction being conducted under controlled conditions whereby the production of pentafluoroethane is minimized.
