2.Liquid-liquid equilibria data for musk ketone, muskxylene, 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.
3.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 muskxylene was richened in heptane (or cyclohexane) phase.
