Cupferron Usage And Synthesis

Analysis reagents	Cupferron is an important analytical reagent, as Ammonium salt of N- nitroso hydroxylamine, commonly known as cupferron. It is usually white or light yellow bright flake scrystal, with sweet odour, long home to darken due to slow decomposition, but in fact can also be used in the analysis. It is soluble in water, benzene, alcohol, ether. The reagent is thermally decomposed to prepare nitrobenzene. Unstable in light and air, we need to save itin a brown reagent grinding mouth bottle, usually place a small amount of ammonium carbonate in bottle packaged with paper or cloth good as a preservative, store in a sealed dark cool place. It can be used as a precipitating agent and solvent extraction agent of copper, iron, tin, titanium, vanadium, chromium and other elements, as a masking agent for the determination of rare earth. Nitrobenzene is reduced with zinc powder in an aqueous solution of ammonium chloride to get phenylhydroxylamine, which is then dissolved in ether, lead to excessive ammonia, and addn-butyl nitrite, then get cupferron, can form a stable five-membered ring chelate with metal ions, therefore, it is common organic precipitant. It can quantitatively measure Fe3 + ions in the acid solution, can also be measure Cu2 +, Sn4 +, Ti4 +, Ga3 +, Hf4 +and other ions, and vanadate (VO-3, VO3-3). When Fe3 +, Cu2 + ions mixedwith other metal ions together, the reagent can be used to separate them out. It is a chelating extractant for Al3 +, Au3 +, Be2 +, Co2 +, La3 +, Pu4 + and other ions, a masking agent for rare earth metal ions. The above information is edited by the chemicalbook of Yan Yanyong.
Purification method	Ddd 30g powdered crude into 120ml60 ℃ water, make it all dissolved, add 2g of powdered activated carbon and stir for 10 ~ 15min, filtrate with the calcined Buchner, and cool the filtrate to 10 ~ 15 ℃, then cool to 0 ℃ overnight. Suction filtration by using a glass filter to precipitate crystals, wash with 10ml ethanol and then wash with 10ml of ether, and dry in air. Cupferron can also be recrystallized with ethanol to purify.
Chemical properties	It is white or cream colored flaky crystals. Melting point is 163-164 ℃, it is soluble in water and alcohol.
Application	It is used as polymerization inhibitor, due to unique polymerization inhibition characteristics of cupferron, also the amount is small, can be used as an alternative of phenol polymerization inhibitor BHT, which is current largely applicated. It is used for colorimetric determination for the weight of aluminum, bismuth, copper, iron, mercury, zinc, manganese, niobium, gallium, tantalum, thorium, titanium, vanadium, tin and other elements of. It is used for quantitative determination of iron in the strong acid solution, quantitative analysis of vanadate, separation of copper and iron together with the other metals, as a masking agent for measuring rare earths.
Production method	Benzene hydroxylamine ether solution was cooled in an ice bath, lead to an excess of ammonia, while stirring and continue adding the ammonia, solution of n-butyl nitrite was added for about 1h, then stir for 15min. Filter precipitate of cupferron, wash with diethyl ether, dry to get products. The product should be stored in a brown glass bottle, the bottle is placed a small amount of ammonium carbonate wrapped by paper (or cloth) as a stabilizer.
