Abstract
Several racemates have been resolved on home-made microcrystalline cellulose triacetate (MCTA) plates eluted with aqueous - organic mixtures containing methanol, ethanol, or 2-propanol. The roles of the chemical structures of the solutes and of the type and concentration of organic solvent on the resolving capability of this polysaccharide have been evaluated. Detection of enantiomeric mixtures in the ratios 50:1, 100:1, and 200:1 was performed by scanning densitometry of the MCTA chromatograms.
