PROCESS FOR DETERMINATION OF WEIGHT PART OF DIPHENYLAMINE AND ITS NITROSO- AND NITROSUBSTITUTED IN PYROXILINE POWDERS BY THE METHOD OF RETURN PHASE LIQUID CHROMATOGRAPHY

摘要

A process for the determination of weight part of diphenylamine and its nitroso- and nitrosubstituted in pyroxiline powders by the method of return phase liquid chromatography relates to the analytical chemistry and consists in decreasing of time for the preparation of sample for chromatography, elimination of the equipment for extraction and filtration.
