Vapor-liquid equilibrium in the hexane-benzene system in presence of petroleum sulfoxides and petroleum sulfones, which are new selective solvents for aromatic and unsaturated hydrocarbons was studied. Liquid-vapor equilibrium were studied in the Bushmakin apparatus under atmospheric pressure. Gas-liquid chromatography with the aid of a UKh-2 chromatograph with a katharometer detector was used for monitoring the purity of hexane and benzene and for analyzing the phases. The stationary liquid phase was 15% Carbowax 20M on Chezasorb (50-70 mesh). A stainless-steel spiral chromatographic column 4 m long and 4 mm inside diameter was used, the temperature was 95/sup 0/C, and nitrogen was used as the carrier gas. Reagents of cp grade were used in the experiments.
