Abstract
A process is described for non-cyclic paraffin isomerization under strong acid conditions in which an adamantane hydrocarbon is used to substantially increase the reaction rate of the isomerization.
Claims13
An isomerization process comprising contacting a C.sub.4 -C.sub.6 non-cyclic paraffinic hydrocarbon with a strong acid system in the presence of an adamantane hydrocarbon containing at least one unsubstituted bridgehead position, at a temperature of about -100.degree. to 150.degree. C., thereby producing a branched isomer of said paraffinic hydrocarbon.
