Abstract
Abstract The separation of seventeen DNP derivatives of amino acids, 2,4-dinitroaniline and 2,4-dinitrophenol by polyamide layer chromatography is investigated. Convenient procedure for the preparation of durable polyamide layers are described. A table of RF values in ten solvent systems and ultraviolet contract photographs of three one-dimensional chromatograms and three two-dimensional chromatograms are given. The present method is better than paper on thin-layer chromatography in speed and efficiency.
