  2-Ethylhexanoic acid N',N'-dibutylhydrazide (DBH) and N',N'-diheptylhydrazide (DHH) were synthesized. The existence regions of copper (II), zinc(II), nickel(II), and cobalt(II) complexes formed upon extraction with DBH in kerosene were studied. The neutral complex ML2 extracted over a wide pH range (from pH similar to 6 to similar to 4 C-NH3 mol/L) is formed only by copper(II), while zinc(II), nickel(II), and cobalt(II) react with DBH to yield precipitates that float at pH 7-9, 9-10.5, and 9.5-11, respectively. On the basis of IR spectra, elemental analysis, and properties, a structure was suggested for the CuL2 complex with DBH. The DBH and DHH complexes with copper(II) are readily stripped with H2SO4 and H2SO4 + CuSO4 solutions. The capacity of a 1.5 mol/L DHH in kerosene with respect to copper(II) is 26 g/L.
