中文摘要:

      利用等体积饱和法气体溶解度实验系统首次测量了温度为293.00~333.00K、压力为0.70MPa~4.00MPa内O2在庚酸乙酯中的溶解度数据，溶解度的相对扩展不确定度小于4 %。实验结果表明：O2在庚酸乙酯中的溶解度随着压力升高而增大，随温度升高而减小。利用NRTL方程对溶解度实验数据进行了关联，计算结果与实验数据之间的平均绝对偏差为1.6%。

英文摘要:

      The solubility of O₂ in ethyl oenanthate was measured in an experimental system established based on the isochoric saturation method at the temperature range of 293~333K and pressure range of 0.7MPa~4.0MPa. The relative expanded uncertainty of solubility measurement is less than 4 % (k=2). Experimental data was correlated well with NRTL equation.
