Liquid—liquid equilibrium studies on hydrocarbon (C10C20)—sulfolane systems

Abstract Equilibrium tie line data have been determined at 60 and 100°C with sulfolane and five model hydrocarbon mixtures consisting of butylbenzene—dodecane, hexylbenzene—dodecane, hexylbenzene—cetane, octylbenzene—dodecane and octylbenzene—cetane. The data so obtained have been predicted by UNIFAC and correlated by NRTL and UNIQUAC model equations. The alkylbenzenes used in the study were prepared in the laboratory.
