Preparation of 2,6-dimethyldecalin and its isomers

摘要

Methods employing a catalyst system comprising a hydrogen fluoride solution of tantalum pentafluoride and/or niobium pentafluoride for the preparation of 2,6-dimethyldecalin from a 12 carbon atom-containing dicyclic naphthenic isomer thereof and for the preparation of a mixture of 2,6-dimethyldecalin and a 12 carbon atom-containing dicyclic naphthenic isomer thereof from methylcyclopentane and/or cyclohexane are disclosed.
