摘要： 用气液色谱法测量了C6～C8芳烃在芳烃衍生物中的无限稀活度系数。以Hildebrand-Scatchard-Flory-Huggins公式进行处理,得到了非极性或微极性溶剂的溶解度参数δ,以修正的Hildebrand-Scatchard-Flory-Huggins公式进行处理,得到了芳烃溶质与各极性溶剂相互作用常数l12。

关键词: 无限稀活度系数, 溶解度参数, 相互作用常数

Abstract: The thermostat of the gas chromatograph is a well stirred liquid bath, in which the column temperature is to be kept within±0.01℃.The infinite dilution activity coefficients of C6~C8 aromatics, namely, benzene,toluene,ethylbenzene,p-xylene,m-xylene and o-xylene in aromatic derivative, dibenzyl, diphenylmethane, diphenylacetylene, 4-benzylbiphenyl, benzophenone, dibenzylether, diphenylamine, N, N-diphenylformamide and diphenylsulphoxide, all of them contained two or three aromatic rings have been measured.

Key words: Infinite dilution activity coefficient, Solubility parameter, Interaction constant
