摘　　要：利用气液色谱法测定了正己烷在正十六烷～正二十三烷、角鲨烷、角鲨烯、二苯甲烷、联苄、丁二酸二正丁酯、丁二酸二异辛酯、已二酸二正辛酯、癸二酸二正辛酯中不同温度下的无限稀活度系数。由Ｆｌｏｒｇ－Ｈｕｇｇｉｎｓ理论预测的正己烷的活度系数与实验值相近，由此进一步得到了二组分体系的相互作用参数值及各溶剂的溶解度参数值。The activity coefficients of n-hexane at infinite dilution in the solvents n-hexadecane-ntricosane, squafane, squalene, diphenylmethane, dibenzyl, di-n-butyl succinicate, di-isooctyl succinicate, di-n-octyl adipate, and di-n-octyl sebacate have been determined at various temperatures using gas liquid chromatography. The Flory-Huggins theory can be used to predict the activity coeffi'cients of n-hexane systems. The interaction parameters and solubility parameters of solvents were obtained.
