| 摘 要： | 用气相色谱法分别测定了苯、甲苯、乙苯、正庚烷、正辛烷、正壬烷和正癸烷在三甘醇和四甘醇中的无限稀释活度系数 ,测定温度范围为 5 0～ 13 0℃。用修正的UNIFAC模型 (Dortmund)对上述不同温度下的无限稀释活度系数实验数据进行关联 ,得到了三甘醇和四甘醇与其它基团的相互作用参数 ,并将计算结果与实测值进行了比较。

| Abstract: | The infinite dilution activity coefficients for benzene,toluene,ethylbenzene, n -heptane, n -octane, n -nonane, n -decane in triethylene glycol and tetraethylene glycol are experimentally measured with gas-chromatography at 50～130 ℃.The experimental data were correlated with the modified UNIFAC (Dortmund) method to obtain the group interaction parameters.The experimental data agreed well with the calculated results. |
