Abstract

This paper reports a number of original thin layer chromatography enantioseparations of closely related ketones and alcohols such as tetralones, indanones, and benzhydrols carried out by elution with aqueous-alcoholic mixtures at different ratios. In order to investigate the structural and substituent effects on chiral recognition of microcrystalline cellulose triacetate, the results were compared with those obtained in previous papers for analogous compounds in similar experimental conditions. Even though the inclusion model of retention of analytes on this chiral stationary phase is confirmed, different and unexpected results were obtained for compounds having very favourable characteristics for resolution.
