Patent

CA 2022729

The invention relates to new catalysts useful for liquid-phase fluorination of halogenated aliphatic hydrocarbons, particularly chlorinated derivatives of ethane and ethylene. These catalysts consist of mixtures of an antimony trihalide and a titanium tetrahalide. Such mixtures are much more effective than each halide taken separately.

L'invention concerne de nouveaux catalyseurs utiles pour la fluoration en phase liquide d'hydrocarbures aliphatiques halogénés, notamment celle de dérivés chlores de l'éthane et de l'éthylène. Ces catalyseurs sont constitués de mélanges d'un trihalogénure d'antimoine et d'un tétrahalogénure de titane. De tels mélanges s'avèrent être beaucoup plus efficaces que chaque halogénure pris séparément.
