The Behaviour of Some Phenolic Acids and Aldehydes on Thin Layers of Silica Gel Impregnated with Fe(III)

Abstract

The behaviour of phenolic aldehydes and acids commonly found in lacustrine sediments as degradation products of lignine was tested by thin layer chromatography on silica gel plates plain and impregnated with Fe(III) in different solvent systems. The differences expressed as R_i values can be used as one of the parameters in the identification of some phenolic aldehydes or acids.
