Summary
Aromatic nitro compounds with hydroxyl, amino, hydrazino, aldehyde, methoxy and halogen substituents were chromatographed in liquid-solid systems of the type cyclohexane+polar solvent — magnesium silicate or Florisil. The effect of the molecular structure on the slopes of the log k′ vs. log XS and RM vs. log XS plots (XS — mole fraction of the polar component in the developing solvent) is interpreted in terms of a molecular adsorption model elaborated originally for silica. For some solutes TLC data are compared with the results of analogous column experiments.
