Abstract
Il a été découvert que de l'antimoine fortement fluoré, notamment en tant que produit d'addition d'acide fluorhydrique, peut s'utiliser comme catalyseur d'isomérisation pour isomériser des composés hydrocarbures halogénés déterminés. Du 1,1,1-trifluoro-2,2-dichloréthane peut par exemple être produit à partir de 1,1,2-trifluoro-1,2-dichloréthane. Le procédé selon l'invention s'utilise également pour purifier des composés hydrocarbures déterminés contaminés par des composés isomérisables.
