ResumoBenzaldehyde 2.4-DNPH and 19 mono-sbustituted benzaldehyde 2,4-DNPH's have been chromatographed by thin-layer techniques. Conditions are reported for the separation of ten of the substituted compounds from binary mixtures with benzaldehyde 2,4-DNPH. Comparisons are reported of Eastman Chromagram precoated sheets with glass plates and of Desaga tanks with Chromagram sandwiches.
