摘要: 研究了不同稀释剂中TBP对醋酸的萃取,其萃取能力在不同稀释剂中按甲苯>苯>环己烷>煤油>四氯化碳>氯仿>甲基异丁基酮的顺序变化。求出了萃取反应的焓变,建立了萃取平衡常数与稀释剂物理参数间的经验方程,并用红外光谱对萃取机理进行了研究。

Abstract: The extraction of acetic acid with TBPin different diluents was studied.The decreasing order of extraction ability of TBPis as follows:toluene,benzene,cyclohexane,kerosene, tetrachloride, chloroform and methyl isobutylketone.The effect of temperatureon the extraction equilibrium was also investigated and the enthalpy of the extraction was obtained.The relationship between the extraction equilibrium constants Kex,and the physicalparameters of diluents can be derived.The extraction mechanism and equilibrium were examined by measurements of IRspectrophotometry.

Key words: Acetic acid, TBP, Extraction, Diluent
