    Abstract: Selective formation of 2,5-dimethylhexadiene-2,4, or mixtures of the same with the corresponding 2,5-dimethylhexadiene-1,4, or of the latter with 2,5-dimethylhexadiene-1,5 in good yield is achieved by the vapor phase ring opening dehydration of 2,2,5,5tetramethyltetrahydrofuran, using alkali or platinum selected metal oxide catalysts at varying temperatures and liquid hourly space velocities.
