摘　　要：在288.15～328.15K下,用光度法测定RbBPh_4在直链一元醇中的溶解度.计算并讨论RbBPh_4由水至直链一元醇中的标准迁移热力学函数,经微机曲线拟合给出△_(tr)G-w→s,△_(tr)S_w→s随温度及碳原子数的经验关系:△_(tr)G_w→s=-20.3504+6.6005×10^(-5)T^2+(14.6628lgn)/(1-7.7713×10^(-9)T^3)△_(tr)S_(w→s)=-0.1320T-(3.4185×10^(-4)T^2lgn)/(1-7.7713×10^(-9)T^3)~2用Born模型及单层结构模型对标准迁移自由能变化规律进行定性与定量的解释.Solubilities of RbBPh4 in water, methanol, ethanol, 1 - propanol, 1 - butanol, 1 -pentanol , 1 - hexanol , 1 - hepanol and 1 - octanol at 288 . 15 ~ 328 . 15K have been determined by spectrophotometry. The standard transfer thermodynamic function of RbBPh4 from water to straight - chain alkanols at 288. 15 ~ 328. 15K has been calculated. The results can be experssed asFurthermore, the contribution of microscopic interaction to the standard Gibbs energy of transfer of RbBPh4 was calculated and discussed.
