    Abstract: Process for synthesizing 1,1,1-trifluoroethane (143a) in the gaseous phase by reacting 1,1-defluoro-1-chloroethane in gaseous phase in the presence of a Cr catalyst. The process may be run isothermally or adiabatically, without co-feeding air or other oxygen containing gas, in the presence or absence of a Ni, Co, Zn or Mn cocatalyst for the Cr catalyst. The catalyst may be unsupported or supported with a support preferably selected from activated carbon, alumina and fluorided alumina. The formation of olefin byproduct can be kept to less than 10 ppm in accordance with the process of the invention.

    Abstract: Process for synthesizing 1,1,1-trifluoroethane (143a) in the gaseous phase by reacting 1,1-difluoro-1-chloroethane in gaseous phase in the presence of a catalyst selected from the SbV, TiIV,and SnIV salts. The process may be run without co-feeding chlorine gas as a coactivator, in the presence or absence of an impurity selected from HCl and 141b. The catalyst may be unsupported or supported on activated carbon. The formation of olefin byproduct was not detected when the process of the invention was conducted under the conditions described.

    Abstract: Process for adiabatically hydrofluorinating hydrochlorocarbons and hydrochlorofluorocarbons in the gaseous phase in the presence of a catalyst that is active at the initial reaction temperature and remains highly selective at the maximum reaction temperature, e.g., a Cr catalyst. The molar ratio of HF to starting compound is at least about 2.5:1. The initial reaction temperature is selected such that the HF in the feed is partially associated but not completely (HF)₆. The catalyst may be unsupported or supported.
