ABSTRACT:
In one embodiment of this invention, a process for alkylating C.sub.3 -C.sub.6 alkanes (paraffins) with C.sub.3 -C.sub.6 alkenes (monoolefins) employs a catalyst composition which has been prepared by heating a mixture consisting essentially of aluminum chloride, at least one metal sulfate (CuSO.sub.4, FeSO.sub.4, NiSO.sub.4, MgSO.sub.4, CaSO.sub.4 or combinations thereof), at least one inorganic refractory support material (alumina, silica, silica-alumina, aluminum phosphate, aluminum phosphate/oxide or combinations thereof), and at least one chlorinated hydrocarbon (preferably carbon tetrachloride). In another embodiment of this invention, a process for alkylating C.sub.3 -C.sub.6 alkanes with C.sub.3 -C.sub.6 alkenes employs a catalyst which has been prepared by heating a mixture consisting essentially of aluminum chloride, aluminum phosphate, silica, and at least one chlorinated hydrocarbon (preferably carbon tetrachloride).
