The influence of addition of a primary amine with a long alkyl branch (Am) on the palladium extraction with 2-hydroxy-4-(1-methylheptoxy)-benzophenone oxime(HL) was studied-in both thermodynamic and kinetic aspects. The complex anion of chlorine with palladium is much more easy to associate with amine either at the interface or in the aqueous phase. The substitution reaction of the associate is more liable to be performed by β-hydroxyoxime kinetically than that of the complex anion of chlorine with palladium, The role of primary amine as a catalyst for speeding the substitution reaction involving Pd exiraction by β-hydroxyoxime has been examined and confirmed in this paper.
