| 摘 要： | 利用红外光谱研究二（2-乙基己基）磷酸和磷酸三丁酯络合萃取邻氨基苯酚在不同情况下的反应机理。结果表明：二（2-乙基己基）磷酸主要与邻氨基苯酚的—NH2发生反应,与邻氨基苯酚的阳离子和中性分子络合。萃取过程存在离子交换和离子缔合两种机制,生成相同结构的萃合物;而磷酸三丁酯主要与邻氨基苯酚的—OH发生反应,与邻氨基苯酚的中性分子发生氢键缔合,生成相同结构的萃合物;两种情况下生成萃合物的结构都与pH无关。

| Abstract: | Reactive mechanism of OAP react with di（2-ethylhexyl）phosphoric acid and tri-nbutyl phosphate in different condition were studied by Fourier transform infrared spectrophotometer （FTIR）. The di （2-ethylhexyl）-phosphoric acid reacts with -NH2 of OAP （cation and neutral molecule of OAP）through iron-association and iron-exchange reaction, and two extracted compound have the same structure. While tri-n-butyl phosphate react -OH of OAP （neutral molecule of OAP） through hydrogen bonding. The pH values have no effect on the structure of the complex formed. |
