摘　　要：测得磷酸三丁脂（ＴＢＰ）萃取苯酚和间甲酚的平衡等温线，表明ＴＢＰ具有很高的萃取分配比，探讨了盐析效应。采用双对数斜率法和连续变量法分别测得ＴＢＰ与苯酚、间甲酚的萃合物的组成比。根据Ｃｌａｕｓｉｕｓ－Ｃｌａｐｙｒｏｎ方程测得萃取反应的焓变△Ｈ值，并观察了负荷有机物的红外光谱，确定了萃含物的结构。The isotherms of the extraction equilibrium have been given.The distribution ratios of phenol and m-cresol were shown to be very high in the extraction by tri-n-butyl-phosphate(TBP).In this investigation salting-out effect was studied.By means of the methods of doublelogarithmic slope and continuous variations,the composition of the extracted species between TBP and phenol,m-cresol was deduced respectively.Employing Clausius-Clapyron equation the en thalpy of the extraction reaction was measured and the structure of the extracted species was in vestigated by the infrared spectra of the loaded organic phases.
