Claim Text:
1. A process for producing dimethylhexane comprising: introducing a stream comprising isobutane and a stream comprising 1-butene or a stream comprising isobutane and 1-butene to an alkylation reaction zone to form a reaction mixture, the stream comprising 1-butene or the stream comprising isobutane and 1-butene containing less than about 50 wt % total of 2-butene and isobutene; and alkylating the isobutane and the 1-butene in the alkylation reaction zone in the presence of a haloaluminate ionic liquid catalyst wherein the haloaluminate ionic liquid catalyst comprises a cation selected from one or more of where R 5 , R 6 , R 18-21 are independently selected from C 1 -C 20 hydrocarbons, C 1 -C 20 hydrocarbon derivatives, halogens, and H; under alkylation conditions to form a stream rich in dimethylhexane, the stream rich in dimethylhexane having a ratio of dimethylhexane to trimethylpentane of at least about 2:1.
