Ten cycloketone 2,4-dinitrophenylhydrazones have been chromatographed by thin-layer techniques using Eastman Chromagram sheets coated with silica gel and developed with benzene in Eastman sandwich apparatus. Good separations of all test compounds from binary mixtures with the standard cyclohexanone 2,4-dinitrophenylhydrazone are reported as well as good separations of more complex mixtures of the test compounds. Lack of precision is noted despite a rigorous standardized procedure. Evidence is offered that chromagram sheets differ in adsorbent activity.
