✦ Synopsis

Ethyl, propyl and butyl homologues of phenol have been chromatographed on layers of cellulose impregnated with simple amides (formamide, N-methylformamide and N,N-dimethylforrnamide) using hexane as the mobile phase. The plots of RM value vs. the logarithm of the concentration of the amide in the slurrying solvent used for the preparation of the chromatolayers are linear. The RF values of the compounds studied are shown to be related to the size of the substituent, the degree of substitution of the aromatic nucleus, and the position of the substituents relative to the phenolic group.

A qualitative agreement between the hydrogen-bonding index of SEARS AND KITCHEN and the chromatographic behaviour of the phenols is observed.
