Department of Chemistry, Ravenshaw College, (Utkal University), Cuttack Manuscript received 13 September 1972; accepted 6 April 1972 Separation of a large number of isomeric mixtures of mono and diaryl thioureas, thiazoles and thiazolines have been tried by adopting the techniques of thin-layer and paper chromatography, using as many as twenty solvent systems of various compositions. It has been observed that these mixtures are resolved into their components in almost all the solvents by T.L.C. when such resolution is impossible on paper chromatograms; thus establishing the greater advantage of T.L.C. over P.C. in the separation of mixtures of such isomeric synthetic products.
