| 摘 要： | 通过磷酸三异戊脂(TiAP)萃取苯酚的平衡常数的测定，发现磷酸三异戊脂对苯酚具有很高的萃取分配比，且分相很快；并探讨了盐析效应．采用双对数斜率法测得TiAP与苯酚的萃合物组成，考察了TiAP萃取苯酚的温度效应，根据Van’t Hoff方程求出相关的热力学函数，同时利用IR探讨了萃合物的结构．

| Abstract: | Equilibrium constant (K_(ex)) in extraction of phenol with tri-isoamyl phosphate (TiAP) in kerosene was studied. The results has shown that distribution ratio of phenol was very high, and the aqueous and organic phases were separated quickly. The effect of salting-out agent was also studied. With a method of double-logarithmic slope, composition of the extracted species between TiAP and phenol was derived. By employing the Van't Hoff equation, the corresponding thermodynamic functions were calculated based on the temperature effect. In addition, structure of the extracted species was investigated using infrared spectra of the loaded organic phase. |
