RETENTION BEHAVIOR OF 1,6-ANHYDROHEXOSE AND D-ALDOPENTOSE DERIVATIVESON SILICA-GEL THIN-LAYERS

To study the relation between the chemical structure of solutes and th eir retention behaviour in thin layer chromatography on silica gel, th e retention constant (R-M value) of a series of variously substituted 1,6-anhydrohexose and D-aldopentose derivatives were measured as a fun ction of the composition of eight non-aqueous binary eluents. The slop es and intercepts of the linear relations between the retention consta nts (R-M) and the logarithm of the volume fraction of the stronger elu ent component have been calculated applying in adsorption chromatograp hy well-known Soczewinski equation and discussed in relation to the so lute and eluent characteristics.
