Uses | Used for photometric determination of vanadium, separation of tantalum and niobium, gravimetric determination of scandium, zirconium, molybdenum, beryllium, iron, titanium, aluminum and copper, Colorimetric determination of cerium, cobalt, titanium and vanadium. Determination of iron content in cobalt acetate Photometric determination of vanadium. Separation of tantalum and niobium. Gravimetric determination of scandium, zirconium, molybdenum, beryllium, iron, titanium, aluminum and copper. Colorimetric determination of cobalt, cerium, titanium and vanadium. |
production method | dissolve phenylhydroxylamine in hot water, add sodium bicarbonate, add benzoyl chloride dropwise under stirring, and add sodium bicarbonate several times to keep the reaction solution alkaline. After feeding, continue stirring for 1.5h. Filter out the solid products benzoyl phenylhydroxylamine and dibenzoyl phenylhydroxylamine, after washing with water, remove benzoyl chloride with sodium bicarbonate, and then dissolve benzoyl phenylhydroxylamine in the mixture with concentrated ammonia water (dibenzoyl phenylhydroxylamine is insoluble in concentrated ammonia water), concentrate from the filtrate, cool and precipitate the finished benzoyl phenylhydroxylamine. |
