1. An alkylation process comprising:
contacting a hydrocarbon feed comprising a butane with an olefin feed comprising a butene in the presence of a liquid Lewis acid catalyst and in the absence of hydrofluoric acid in an alkylation reaction zone under alkylation conditions to form a biphasic reaction mixture comprising alkylation products comprising trimethylpentanes and the liquid Lewis acid catalyst, wherein the liquid Lewis acid catalyst is a liquid reaction product of a donor molecule and a metal halide, wherein the metal in the metal halide is Al, wherein the donor molecule comprises caprolactam, N-methylcaprolactam, delta-valerolactone, tetrahydrofuran, caprolactone, alpha-acetolactone, beta-propiolactone, gamma-butyrolactone, morpholine, beta-propiolactam, gamma-butyrolactam, delta-valerolactam, or combinations thereof, wherein a mole fraction of the metal halide in the liquid Lewis acid is greater than about 0.5 to less than about 1;
separating the biphasic reaction mixture into the alkylation products and the liquid Lewis acid catalyst; and
recovering the alkylation products.
