The effect of the substituents of beta-ketoiminato ligand of copper(II) and nickel(II) complexes on their retention on thin layers of polyacrylonitrile
Апстракт
The effect of substituents of the beta-ketoiminato ligand of 24 copper(II) and nickel(II) complexes on hR(F) values obtained by TLC on polyacrylonitrile (PAN) has been studied. Chelate ligands were prepared by condensation of diamine (dm) and the corresponding beta-diketone. Copper(II) and nickel(II) complexes with chelate ligands containing ethylenediamine (en = 1,2-diaminoethane) or propylene diamine (pn = 1,2-diaminopropane) as the amine part and acetylacetone (acac = 2,4-pentanedionato ion) and/or phenylacetylacetone (phacac = 1-phenyl-1,3-pentanedionato ion), and/or trifluoroacetylacetone (tfacac = 1,1,1-trifluoro-1,3-pentanedionato ion), i.e. phenylacetylacetone as beta-diketone, were synthesized. Ten non-aqueous mobile phases (six mono-component and four two-component) and two aqueous mobile phases were used for chromatographic separation. The results revealed that the mobility of the complexes decreased on substitution of the CH3 group in the beta-ketoiminato ligand by CF3 or C...6H5. The chromatographic behavior of the complexes on PAN was compared with that on other adsorbents. Possible separation mechanisms are discussed.
