Complexation and extraction properties of N′,N′-dibutyloctanohydrazide

Abstract

A new extractant for copper(II) extraction, viz., N´,N´ dibutyloctanohydrazide, was syn thesized. Its acid base, extraction, and complexation properties were studied. The introduction of two butyl substituents into the hydrazide group weakens the acidic properties of the com pound synthesized compared to the unsubstituted hydrazide, shifts the region of efficient copper(II) extraction from an acidic medium to weakly acidic and ammonia media, and forms an uncharged extractive copper complex.
