Title
(EN) A PROCESS FOR PREPARING 1,1,1-TRIFLUOROETHANE
(FR) PROCEDE D'ELABORATION DU 1,1,1-TRIFLUOROETHANE
Abstract
(EN)
A process for producing 1,1,1-trifluoroethane by reacting 1,1,1-trichloroethane with hydrogen fluoride in the presence of a fluorination catalyst under conditions sufficient to produce 1,1,1-trifluoroethane but in the absence of a solvent. The 1,1,1-trifluoroethane is useful as a refrigerant, in air conditioners, heat pumps, and as a propellant or blowing agent.
(FR)
Procédé d'élaboration du 1,1,1-trifluoroéthane par réaction de 1,1,1-trichloroéthane avec du fluorure d'hydrogène en présence d'un catalyseur de fluorination dans des conditions suffisantes pour produire 1,1,1-trifluoroéthane mais en l'absence de solvant. Le 1,1,1-trifluoroéthane est employé comme réfrigérant, dans les climatiseurs et les pompes à chaleur, et comme propulseur ou agent de soufflage.
