Abstract (en)
[origin: WO2004078684A1] The inventive method for producing 1,1,1-trifluoroethane (HFC-143a), consists in exposing 1,1-Difluoro-l-chloroethane (HCFC-142b) to a vapour phase reaction with hydrogen fluorine (HF) in the presence of a hydrofluorination catalyst at a molar ratio between HCFC-142b and HF, which is introduced into said vapour phase reaction, equal to or higher than 1 and less than 1.3.
