在 2 8 3.1 5 ,2 88.1 5 ,2 93.1 5 ,2 98.1 5K温度下 ,测定了苯、甲苯、联苯在水 叔丁醇混合溶剂中的溶解度 ,其中混合溶剂中叔丁醇的物质的量分数分别为 0 .0 0 0 ,0 .0 1 0 ,0 .0 2 0 ,0 .0 30 ,0 .0 40 ,0 .0 45 ,0 .0 5 0 ,0 .0 6 0 ,0 .0 80 ,0 .1 0 0 .以此为基础计算了苯、甲苯、联苯在不同温度和溶剂组成条件下的标准溶解Gibbs自由能和相关过程的疏水相互作用Gibbs自由能 ,并从微观上讨论了溶剂结构对溶解度和疏水作用的影响 . The solubility of benzene, toluene and biphenyl in the water-tert-butanol mixed solvent was measured at the temperature of 28.1 5, 88.1 5, 2 93.1 5 and 2 98.1 5K, wherein the amount of t-butanol in the mixed solvent The scores are respectively 0.0000, 0.010, 0.020, 0.030, 0.040, 0.045, 0.050, 0.060, 0 80, 0 1 0 0. On the basis of this, the Gibbs free energy of the Gibbs free energy of the standard dissolution and the Gibbs free energy of the related process under different temperature and solvent composition were calculated, and from the microscopic point The effect of solvent structure on solubility and hydrophobicity was discussed.
