Studies on the thin-layer chromatography of some indanols

Abstract

Indanols have been chromatographed on thin layers of cellulose impregnated with ethyl oleate as the stationary phase, and aqueous ethanol as the mobile phase. The R F values are more reproducible on layers prepared by incorporating the impregnant into the solvent used to slurry the support before coating the layers. Supports impregnated with the stationary phase by chromatographing the impregnant into the prepared layers are less reproducible. R F values determined from chromatograms run in satruation chambers are more reproducible than those determined from chromatograms run in conventional tanks. Results obtained from precoated layers which were impregnated with the stationary phase by the chromatographic method are more reproducible than the results obtained from laboratory prepared plates which were impregnated with the stationary phase and chromatographed under comparable conditions. Some effects of the molecular structure of the indanols on their chromatographic behaviour are discussed.
