Abstract:
A process for removing metal halides from regenerated ionic liquid catalyst comprising interacting a regenerated ammonium-based metal-halide ionic liquid catalyst or an ammonium-based metal-halide ionic liquid catalyst undergoing regeneration with either the parent ammonium halide salt from which the ionic liquid catalyst was made or a corresponding mixed salt having an ammonium halide to metal halide molar ratio of 0 to less than 2.0 is disclosed.
