The separation of complexible ligands using alkylation inhibitors.

摘要

In processes in which liquid sorbents which are solutions in an aromatic hydrocarbon or halogenated aromatic hydrocarbon of 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 comprising 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 zinc diphenyl or triphenylboron.
