Abstract

Acyclic and alicyclic aliphatic hydrocarbons are isomerized by contacting the same with hydrogen in the presence of a difficultly reduceable metal halide in combination with at least a molar equivalent of hydrogen halide. The preferred catalyst system is tantalum pentafluoride, niobium pentafluoride or their mixtures in combination with at least a five-fold molar excess of hydrogen fluoride.
