Prediction of Rf in a mobile phase which is a binary mixture of a strong and weak solvent by using either a second order or a third order polynomial equation, based on the mole fraction of the strong solvent as the independent variable and p-nitrobenzyl esters of 15 dansyl amino acids as model solutes for TLC on silica gel with each of 5 different mobile phases. Discussion of the accuracy of the prediction.

      J. Planar Chromatogr. 12, 301-305 (1999). HPTLC of 25 2-cyano-3-methylthio-3-substituted amine acrylates on RP 18 with methanol - water mixtures (from 65 to 90% in 5% steps). Detection under UV. It was shown that the retention data of a compound can be predicted from structural parameters; it is thus possible to predict the retention of a compound without synthesizing it which is of particular interest in molecular design investigations.

      Correlation of retention parameters of pesticides in Normal and RP Systems and their Utilization for the Separation of a Mixture of Ten Urea Herbicides and Fungicides by Two-Dimensional TLC on Cyanopropyl-Bonded Polar Stationary Phase and Two-Adsorbent-La
      T. TUZIMSKI*, A. BARTOSIEWICZ (*Department of Inorganic and Analytical Chemistry, Medical University, Staszica 6, 20-081 Lublin, Poland, ttuzim@panaceum.am.lublin.pl)

      Chromatographia 58 (11-12), 781-788 (2003). Ten urea herbicides and fungicides have been separated by use of two-dimensional thin-layer chromatography. The largest differences are obtained by combination of normal-phase (NP) system and reversed-phase (RP) system on cyanopropyl-bonded polar adsorbents and on two-adsorbent layer containing a narrow zone of octadecyl silica and adjacent a wide zone of silica (or vice versa). The greatest spread of points was obtained for combination of nonaqueous NP systems with ethyl acetate on silica and RP systems comprising a polar solvent (methanol) in water on octadecyl silica adsorbent wettable with water (RP-18W). A good spread of points was also obtained for pairs of normal-phase systems with heptane-ethyl acetate mobile phases and reversed-phase systems with water-dioxane mobile phases, both on cyanopropyl-bonded polar adsorbents. The correlations of Rf values in NP/RP systems were utilized in practical separation of a mixture of ten urea pesticides using 2D-TLC on these adsorbents. The plates were scanned and videoscanned showing the real pictures of TLC chromatograms.

      Linkage between separation of Cu2+, Co2+, and Ni2+ on TLC and crystal field theory
      S. ERGÜL (Department of Science Education, Faculty of Education, Ondokuz Mayis University 55200, Atakum Yerleskesi-Samsun, Turkey)

      J. Chromatogr. Sci. 46 (10), 907-911 (2008). Examination of M(DEDTC)2 (M = Cu, Co, or Ni) and M(PyDTC)2 (M = Cu or Co) complexes prepared by reactions of sodium diethyldithiocarbamate (NaDEDTC) and ammonium pyrrolidinedithiocarbamate (NH4PyDTC) with metal (II) nitrates. Qualitative analysis and separation using TLC systems in the literature. Reexamination and discussion of the already known separation behaviour of the mentioned metal cations and their complexes in the context of relation to the crystal field theory (CFT) and TLC. Based on the chromatographic data it was found that CFT is closely related to the TLC separation of these metal cations and their complexes. This study is useful in understanding the linkage between the CFT of coordination chemistry and the chromatographic parameters, e.g., hRf value and theoretical plate numbers of the complexes.
