Paper chromatograms of sodium halides such as chloride, bromide, and iodide dissolved in water or in aqueous caustic soda of various concentrations, were studied with butanol-picoline, butanol-propanol, or butanol-ammonia as a developing solvent, in order to identify such halides surely by their RF values on chromatograms, and further to apply the result for the identification of halogens contained in organic substances. The spots of halides after development were revealed by their brown coloration of silver sulfide through silver halides. Iodide was rather better identified by means of a characteristic starch method. It was found that butanol-picoline was a suitable solvent to separate spots of the three halides completely, and that these suffered little influence on R_F value or on shape from caustic soda contained in solutions, so far its concentration being within ca. 1.5 N. Sodium cyanide and sulfide. and potassium rhodanate were also chromatographed and found that they located quite separated from halides and gave no disturbance for identification of the latters. On chromatographing a few drops of the decomposition solution with sodium (the alkaline concentration being within the limit quoted above) of various organic substances, which, in addition to halogen, may sometimes contain either nitrogen or sulfur, or both together, halogens contained were identified quite satisfactorily based on the results obtained above.
