摘　　要：利用气液色谱法测定了C9芳烃在邻苯二甲酸二甲酯中的热力学参数，同时用本法测定了苯、甲苯、乙苯在正十八烷中的无限稀释活度系数，并与文献值进行了比较，证明该方法省时省力、消耗少、结果可靠。Thermodynamic coordinates of C_9 aromatic hydrocarbons in dimethyl (o-) phthalate were determinated by gas-liquid chromatography. The infinite dilution activity coefficients of benzene,methylbenzene and ethylbenzene were also determinated by the method. Compared with lecture, this method was economy and results was reliable.
