Abstract
A compound, monochloro biphenyl: CuAlCl.sub.4, has been isolated and proven to exist. Monochloro biphenyl can be any one of the possible three isomers, ortho, meta and para or can be any mixture of the three isomers. An improved process is provided for the separation of olefins, acetylenes, carbon monoxide or hydrogen sulfide from gaseous feedstreams. A solvent is made by dissolving CuAlCl.sub.4 in a liquid mixture of monochloro biphenyls. This solvent is used to contact the gas feedstream and dissolve by complexation the ligand part of the feedstream. The ligand-fat solvent is separated from the gas feedstream and the ligand recovered by running the solvent through an atmospheric reboiler and one or more reboilers under vacuum. The gas streams of the reboilers are combined and after cooling are a nearly pure stream of the separated ligand. Solutions of CuAlCl.sub.4 in monochloro biphenyls are a low-viscosity, high ligand-solubility and rapid-equilibrating solvent for the separation of ligands (olefins, acetylenes, carbon monoxide and hydrogen sulfide).
