Disclosed is an alkylation process. The process comprises contacting a hydrocarbon mixture comprising at least one olefin having from 2 to 6 carbon atoms and at least one isoparaffin having from 3 to 6 carbon atoms under alkylation conditions in the presence of an acidic ionic liquid catalyst. The catalyst comprising a mixture of at least one acidic ionic liquid and at least one alkyl halide. The acidic ionic liquid is a chloroaluminate ionic liquid prepared by mixing aluminum trichloride (AlCl 3 ) and a hydrocarbyl substituted pyridinium halide having the general formula A:
where R = H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and X is a chloroaluminate; and wherein the isoparaffin and the olefin are alkylated. |
