The infinite dilution activity coefficients of C6 hydrocarbons (hexane, 3-methylpentane, cyclohexane and benzene) in heavy paraffinic hydrocarbons (hexadecane and eicosane) were measured in the region 20∼80°C by using a gas stripping method. The UNIFAC-FV model was applied to calculate the infinite dilution activity coefficients. Those of hexane and 3-methylpentane are predicted sufficiently by the model. Further, those of cyclic compounds such as cyclohexane or benzene can be correlated by adjusting the shape parameters in the combinatorial term.
