US Patent:

43072623, Dec 22, 1981

Filed:

May 28, 1980

Appl. No.:

6/153977

Inventors:

Paul C. Ostrowski - Webster TX

Assignee:

Tenneco Chemicals, Inc. - Saddle Brook NJ

International Classification:

C07F 108
C07F 306
C07C 7156

US Classification:

585848

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 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 a small amount of zinc diphenyl.
