Chromatographic Separation on Silica of Polar Aromatic Compounds

Abstract Our goal in this work, was to seek the best experimental conditions which allow the migration and partition in thin layer chromatography of numerous aromatic compounds, essentially those of polar character, according to a predominating adsorption process. We then studied the modification of different coefficients intervening in these chromatographies according to accepted experimental conditions. The results with different modes of adsorbent deactivation show that the adsorption process is possible and must be interpreted by the SNYDER Model.
