Determination of Association Effects in TLC Data for Different Solutes Chromatographed in Methanol-Acetone on Silica Gel

Abstract The TLC data for different solutes chromatographed in methanol-acetone mobile phase on silica gel at 293 K are analysed by means of the theoretical equations discussed in the previous paper (1). This analysis shows that for the above systems the solute-solvent and solvent-solvent association and the composition of the surface phase play an important role. The composition of the surface phase has been determined by utilizing the excess adsorption data of methanol from acetone on silica gel.
