摘要
测定了酮麝香、二甲苯麝香在单一溶剂和混合溶剂中的溶解度以及酮麝香的中间体 2 ,6 二甲基 4 叔丁基苯乙酮在不同溶剂中的溶解度 ,并且测定了多溶质多溶剂体系的固液平衡 ,采用UNIFAC活度系数法进行以上体系的固液平衡计算 ,计算结果与实验测定结果吻合良好。采用文中提出的方法不仅可以预测多溶质体系在溶液中共同达到饱和时的溶解度 ,而且可以预测部分溶质达到饱和时的溶解度 。
The solubility of musk ketone and musk xylene in various solvent at various temperature is measured.The solid liquid equilibria of several kinds of systems such as one solute one solvent system,one solute two solvents system and muti solutes multi solvents system are studied experimentally and calculated by UNIFAC.The experimental results agree well with those calculated.For a multi solutes system containing unsaturated solutes,the solutes dissolved in the solvent but not saturated can be taken as components of the solvent when we calculate the solubilities of the saturated solutes.It provides a method to calculate the solubility of product with impurities in the process of solution crystilization.
