METHOD OF PHOTOCOLORIMETRIC DETECTION OF ASYMMETRICAL DIMETHYLHYDRAZINE IN AQUEOUS SOLUTIONS

摘要

FIELD: analytical control of compounds exhibiting toxic properties. SUBSTANCE: hydroxylamine of hydrochloric acid and sodium hydroxide are injected into analyzed substance, prepared mixture is blown through with inert gas during boiling, dimethylhydrazine released with it is let pass through mixture of n-nitrobenzaldehyde in ethyleneglycol and acetic acid with subsequent photometering of obtained solution. EFFECT: increased authenticity of method. 2 tbld
