Abstract of the Disclosure In processes in which liquid sorbents that are solutions in an aromatic hydrocarbon or halogenated aromatic hydrocarbon Or a bimetallic salt complex having the generic formula MIMIIXn'Aromatic, wherein MI is a Group I-B metal, MII is a Group III-A metal, X is halogen, n is the sum of the valences of MI and MII, and Aromatic is a monocyclic aromatic hydrocarbon or halogenated aromatic hydrocarbon are used to separate complexible ligands from a gas feedstream that comprises an olefin having 2 or 3 carbon atoms, alkylation of the aromatic hydrocarbon or halogenated aromatic hydrocar- bon is inhibited by incorporating in the liquid sorbent from 8.5 mole percent to 30 mole percent, based on t? Group I-B metal in the liquid sorbent, of an amine-aluminum chloride adduct, such as ammonia-aluminum chloride adduct or pyridine- aluminum chloride adduct.
