| Abstract: The dissociation constants of three hydroxamic acids n-C7H15CONHOH,α,ω-(CH2)5-(CONHOH)2, p-C6H4(CONHOH)2 in aqueous solution were pH-metrically determined in the presence of 0.1 mol·l-1NaCl at 30.0± 0.1℃. The three new solid complexes of tungsten(Ⅵ)-hydroxamates WO2(n-C7H15CONHO)2, WO2[α,ω-(CH2)l(CONHO)2], W2O5-[p-C6H4(CONHO)2]·2H2O were synthesized and characterized by ekmental analysis, solubility,molar conductance, infrared spectra and thermogravimetric studies. |
