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 an aromatic hydrocarbon or halogenated aromatic hydrocarbon are used to separate complexible ligand 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 a small amount of triphenylboron.
