| 摘 要： | 溶剂萃取法处理含酚废水一般选用醋酸丁酯.甲基异丁基酮和异丙醚等N,N,-二甲基庚基乙酰胺(N503)萃取酚已得到实际应用,但酮类水溶性较大,醋酸丁酯等萃取酚的分配系数不及取代酰胺类,常用萃取剂磷酸三丁酯(TBP)也具有良好的萃取脱酚性能,已有磷类萃取剂萃取酚的报道.本文考虑了TBP萃取苯酚的性能,通过在不同温度下分配比的测定,求得萃取反应的热力学函数.用斜率法.连续变量法研究了萃合物的组成,并根据IR和1H NMR讨论了萃取过程与萃合物的结构.

| Abstract: | Phenol extration by TBP in kerosine was studied. The distribution ratios were determine at 0-45? The extration equilibrium constant, free energy, enthalpy, and entropy of extration were calculated The slope method and the method of continuous variations were used to show that composition of the extration complex is PhOH.TBP. The IR and NMR spectra show the existence of intermol. H bonding between PhOH and TBP. |
