AB  - The effect of the electronegativity of donor atoms on RF values obtained by TLC on silica gel was investigated with two series of complexes of the type [M(acac)3-n(phacphac)n] and [M(acac)3-n(phacphSac)n], where M is Co(III), Cr(III) or Ru(III), acac=2,4-pentandionato ion, phacphac=1,3-diphenyl-1,3-propanedionato ion and phacphSac=3-mercapto-1,3-diphenyl-prop-2-en-1-on ion (n=0-3). Development was with nine single and six two-component solvent systems. The RF values of the complexes increase by replacing one oxygen atom of a β-diketonato ligand with a less electronegative sulphur atom. A positive linear dependence between the RM values of the complexes and the numbers of acac substituted by phacphSac ligands was established. The separation mechanisms and separation factors are discussed. © 1993 Friedr. Vieweg & Sohn Verlagsgesellschaft mbH.

AB  - The chromatographic behaviour of ten aliphatic and aromatic amines on thin layers of polyacrylonitrile sorbent was investigated using seven aqueous solvent systems. It was established that an increase in the hydrophobic part of the amines results in their increased retention on this sorbent. A positive linear depencence between the number of carbon atoms in the n-alkyl groups of primary aliphatic amines and the corresponding RM values was also established. The separation of the investigated amines was assumed to be based on non-specific hydrophobic interactions between their non-polar parts and the hydrocarbon chains of the sorbent. © 1992.

AB  - The chromatographic behaviour of six tris(alkylxanthato)cobalt(III) complexes on polyacrylonitrile sorbent thin layers was investigated using four non-aqueous and two aqueous solvent systems. It was assumed that their separation under normal-phase conditions was achieved by the mechanism of hydrogen-bond formation between highly electronegative sorbate oxygen and/or sulphur atoms and sorbent methyne group hydrogens. In contrast, it was assumed that under reversed-phase conditions the separation was based on non-specific hydrophobic interactions. Finally, the linear dependence between the number of carbon atoms in the ligands and the corresponding RM values of the investigated complexes of a homologous series was confirmed. © 1992.

AB  - Acid-base equilibria in heterogeneous and homogeneous systems of some sparingly soluble benzodiazepines (diazepam, prazepam, chlordiazepoxide and medazepam) were investigated in aqueous solution and the corresponding equilibrium constants were determined by the application of pH-metric, spectrophotometric and solubility methods. The sites of protonation were predicted on the basis of the analysis of the corresponding carbon-13 nuclear magnetic resonance spectra. In addition, buffer characteristics of saturated aqueous solutions of these drugs in the presence of the solid phase were investigated and it was established that they possess a very high buffer capacity over a specific pH range.
