Abstract: Extraction experiments are presented dealing with the partition of Cu(II) complexes of 1-alkyl-2-methylimidazoles, 1-alkyl-2-ethylimidazoles,
1-alkyl-2-propylimidazoles, 1-alkyl-2-butylimidazoles, and 1-alkyl-2-pentylimidazoles (where alkyl = ethyl, butyl, hexyl)
between water and an immiscible organic solvent (chloroform, methylene chloride, 2-ethylhexanol, isoamyl alcohol, benzyl alcohol,
methyl propyl ketone, and toluene). It has been shown that the partition ratios of Cu(II) complexes are dependent on the donor
number (DN) of the solvent and the partition ratios increase distinctly with their increase in DN.
Keywords: donor number – solvent extraction – Cu(II) complexes – partition ratio
