Abstract

L'invention concerne un procédé pour préparer du trifluoro1,1,1 chloro-2 éthane. Pour préparer du trifluoro-1,1,1 chloro-2 éthane, éventuellement en melange avec du difluoro-1,1 dichloro-1,2 éthane, on fait réagir du trichloréthylène avec de l'acide fluorhydrique pratiquement anhydre, en présence d'un catalyseur de fluoration constitué d'une combinaison d'un ou plusieurs composés d'antimoine et/ou d'arsenic et d'un ou plusieurs composes de métal de transition. L'invention permet en particulier une préparation industrielle avec des rendements en produits et des rendements spatio-temporels très améliorés.
