ABSTRACT:
In processes in which liquid sorbents that are solutions in an aromatic hydrocarbon or halogenated aromatic hydrocarbon of a bimetallic salt complex having the generic formula M.sub.I M.sub.II X.sub.n.Aromatic, wherein M.sub.I is a Group I-B metal, M.sub.II is a Group III-A metal, X is halogen, n is the sum of the valences of M.sub.I and M.sub.II, 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 hydrocarbon is inhibited by incorporating in the liquid sorbent from 8.5 mole percent to 30 mole percent, based on the 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.
