Adsorptivity of esters of Z- and E-2,3-diphenylpropenoic acids and similar compounds on silica in terms of the Snyder theory. J. Chromatogr. A 758, 135-144 (1997). Study of TLC of 8 Z and E esters of the type C6H5CH=C(C6H5)CO5R using 20 computer-selected mobile-phases on the basis of the Snyder theory, the mobile phases having strength e, equal to 0.165 or 0.250 and different values of localization, m and polarity, p'. Calculation of the energy of adsorption of all groups participating in the solute structures under selected conditions using the available values. Discussion of the adsorptivity and the retention using the ester group in combination with the configuration of the diastereoisomers, and of the tuning effect of p' on e and adsorptivity.
J. Planar Chromatogr. 11, 123-126 (1998). Determination of the lipophilicity and specific hydrophobic surface of thirteen amido esters of ethanolamine by RP-TLC on silica gel impregnated with a 15% solution of paraffin oil in dichloromethane. Development with water - methanol mixtures. Regular retention behavior was observed for compounds studied, their RM values decreased linearly with increasing concentration of methanol in the mobile phase. Visualization under UV 254 nm.
J. Liq. Chrom. & Rel. Technol. 22, 1-14 (1999). Review on the quantitative structure-retention relationship (QSRR) in TLC including a description of the establishment of QSRR, which is based on physico-chemical parameters, non-specific parameters, topological indices, and a combination of physico-chemical parameters. The application of QSSR for prediction of retention, determination of lipophilicity, evaluation of some physico-chemical parameters of chemicals, evaluation of biological activity of compounds, and explanation of separation mechanisms is also reviewed.
Chin. J. Chem. 18, 872-876 (2000). HPTLC of 19 N-(benzothiazol-2-yl)-a-amino alkyl phosphonic diesters on RP-18 with methanol-water mixtures, the concentration of methanol ranging from 75% to 90% in steps of 5%. Detection under UV. The correlation of the chromatographic parameters k' and Rf with the lipophilicity parameter (Clog P) was established. Rapid and simple method; alternative for lipophilicity measurement.
Part II. TLC of some phenols. J. Planar Chromatogr. 17, 9-13 (2004). TLC separation of some phenolic compounds (phloroglucinol, 2-aminophenol, 4-hydroxybenzaldehyde, 4-methoxyphenol, salicylic acid, phenol, 4-tert-butylphenol, 2,4-dichlorophenol, 2,6-dimethylphenol) on CN-phases, silica gel and polyacrylonitrile with 14 different mobile phases at ambient temperature in a HPTLC horizontal developing chamber. Detection by spraying with 0.05 % fluorescein solution in ethanol and subsequent exposure to UV light at 366 nm.
J. Planar Chromatogr. 18, 240-243 (2005). TLC of twenty-one N-benzyl-2-azaspiro[4.4]nonane- and [4.5]decane-1,3-dione derivatives on RP-18 with a mixture of n-propanol and TRIS buffer (pH 7.0) in a chamber saturated for 30 min. Detection under UV light at 254 nm. Examination of chromatographic behavior revealed a linear correlation between RM values and the concentraton of n-propanol in the mobile phase.
Comparison with results obtained by use of computational algorithms J. Planar Chromatogr. 22, 327-331 (2009) TLC of 27 novel imidazo[2,1-c][1,2,4]triazine derivatives together with 12 compounds with known literature log P values (as reference calibration data) on RP-18 with methanol - water binary mobile phases containing different proportions of methanol in horizontal chambers without chamber saturation. Detection under UV 254 nm. Using principal-component analysis the obtained results were compared with results from nine computational methods.
J. Planar Chromatogr. 27, 229-232 (2014). TLC of nine compounds with single point adsorption: diphenylamine (1), indol (2), 2-naphtol (3), 1-naphtol (4), 1-naphtylamine (5), 4-toluidine (6), carbazole (7), 4-chloraniline (8), and thymol (9) on silica gel with six modifiers: acetone, dioxane, hexane, isopropanol, methylethylketone, ethyl acetate, and tetrahydrofurane (in hexane), in six concentrations: 5 %, 10 %, 15 %, 20 %, 30 %, and 40 %. Qualitative determination by absorbance measurement at UV 254 nm. Retention values allowed to consider weighted regression with 1/x weights during retention extrapolation.
