| 摘 要： | 本文计算并测定了酮麝香、二甲苯麝香、二甲基亚砜(或乙腈)和庚烷(或环己烷)四元体系的液液相平衡，试验结果与计算值基本吻合。平衡双液相中两种麝香的比例不同于原料，两液相中两种麝香分别得到了富集，其中二甲基亚砜(或乙腈)相中富含酮麝香、庚烷(或环己烷)相中富含二甲苯麝香，这种液相分相可用于分离麝香混合物。本文的研究为麝香混合物的分离提供了理论指导。此外，采用本文的方法还可以预测较难测定的多元固、液混合物的相平衡关系。

| 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. |
