| 英文摘要 | The equilibrium for the propionic acid extraction by N1923 in three diluents, represented as proton-donator (n-octanol), polar (butyl acetate). inert (hexane) types, have been studied. The diluents had a significant influence on the equilibrium. The loading ratio, Z, was employed to investigate the effect of diluents on the extraction efficiency. When Z(exp) was lower than 1, N1923 extraction followed the order: n-octanol > butyl acetate > hexane. When the loading ratio Z(exp) was higher than 1, the order changed to: butyl acetate > hexane > n-octanol. Equilibrium complex constants K(11), K(21), K(31) have been estimated. The results showed that K(11) Was Much higher than K(21) and K(31), demonstrated K(11) as the dominant factor in the extraction process. Comparing the values of K(11) of all the three diluents. the following order was observed: n-octanol > butyl acetate > hexane. The influence of amine concentration on the extraction equilibrium constant in different diluents was also investigated. The extraction equilibrium constant K(11) decreased with the increase of amine concentration in n-octanol. When hexane and butyl acetate were used as diluent, the extraction equilibrium constant K(11) increased slightly with the increase of amine concentration. (C) 2009 Elsevier B.V.
