Abstract Liquid-liquid equilibria data for musk ketone,musk xylene,dimethyl sulfoxide (or acetonitrile) and heptane (or cyclohexane) quaternary systems were measured firstly to evaluate the effect of the two liquid phase on the separation of musks mixture.Experimental data agreed with those calculated.The compositions of musks in the equilibria liquid phase were different from the feed,that is,musk ketone was richened in dimethyl sulfoxide (or acetonitrile) phase while musk xylene was richened in heptane (or cyclohexane) phase. So this kind of equilibria liquid phase was useful to separate musk ketone and musk xylene.The method proposed could be used to determine the multicomponent solid-liquid phase equilibria which was difficult to obtain.
