【摘要】 用气液色谱法测定若干烃类溶质在二元混合固定液中的无限稀活度系数,所研究的二元混合液为具有不同极性的四种类型:(1)正廿二烷-正十六烷;(2)邻苯二甲酸二壬酯-角鲨烷;(3)环丁砜-碳酸丙烯酯;(4)环丁砜-己二腈。用最小二乘法拟合三元系的Flory-Huggins公式,得到各种相互作用参数。更多还原

【Abstract】 The infinite dilution activity coefficients of some hydrocarbon solutes in binaryliquid mixtures of any composition have been determined by gas-liquid chromato-graphy. The binary liquid mixtures differing in polarity are as follows: n-docosane+n-hexadecane, dinonyl phthalate+squalane, sulfolane+propylene carbonateand sulfolane+adiponitrile. The experimental data have been fitted with the Flory-Huggins formula forternary system by the method of least-squares to evaluate interaction parameters.更多还原
