The multi-component parameter contained in a modified Wilson equation has been acknowledged to be useful for correlating liquid-liquid equilibria of alkane + methanol + aromatic hydrocarbon ternary mixtures, such as heptane + methanol + benzene. The characteristics of the multi-component parameter have been studies and discussed. An estimation procedure for the parameter from pure-component properties is proposed.
