采用气相色谱的分析技术 ,用摇瓶法分别测定了苯 ,甲苯 ,乙苯的溶解度 (Sw)和分配系数 (Kow) .结果表明 ,溶解度和分配系数之间存在线性关系 :lnKow =0 .45 5 8- 0 .9176lnSw .并且运用结构法和摩尔体积法估算了苯及其简单同系物的溶解度和分配系数 .估算结果与实验结果能较好吻合 ,说明估算法是一种简便、可靠的方法
The solubility and partition coefficient (Kow) of benzene, toluene and ethylbenzene were determined by gas chromatography and by shake flask method.The results showed that there was a linear relationship between solubility and partition coefficient: lnKow = 0.45 5 8- 0 .9176lnSw. And the solubility and partition coefficient of benzene and its simple homologues were estimated by the structure method and the molar volume method. The estimation results are in good agreement with the experimental results, indicating that the estimation method is a simple and reliable method
