摘要
采用平衡法测定了温度在293.15 ～353.15 K下双酚A在水、5％、10％、15％、20％和25％NaC1溶液中的溶解度.结果表明BPA溶解度随温度升高而增大,随NaC1溶液浓度增加而减小.分别采用理想溶液模型、λ-h方程和Apelblat模型对溶解度数据进行了关联,总平均相对误差分别为1.88％、2.83％、1.57％,表明三种模型均适用于合电解质的三元物系,能较好地关联BPA的溶解度数据.
The solubilitis of BPA in water, 5% , 10% , 15% , 20% and 25% NaC1 solution at 293.15 -381.15 K were measured with the equilibrium method. According to the experimental data, the solubilities of BPA in a- bove mentioned 6 solvent systems increased with the increase of temperature,but decreased with the increase of concentration of NaC1 solution. The experimental data were correlated with ideal solution model, A-h equation and Apelblat model, respectively. The average relative deviations are 1.88% ,2.83% ,1.57% ,respectively. The results showed that ideal solution model, A-h equation and Apelblat model could well correlate the solubility data of BPA, and the three models also can be applied to the ternary system containing electrolyte.
