What is Hydroxylamine Hydrochloride?
Hydroxylamine hydrochloride is an inorganic compound with the chemical formula NH2OH·HCl, which is usually used as a reducing agent.
Hydroxylamine hydrochloride is colorless monoclinic crystal, easily soluble in water, soluble in ethanol, glycerol, and insoluble in ether. It has strong hygroscopicity and gradually decomposes after being wet. It also decomposes when heated to above 151°C.
Hydroxylamine chloride can reduce the blue cupro ammonia solution to produce a colorless cuprous ammonia solution:
4 [Cu(NH3)4]2+ + 2 NH2OH2+ + H+ → 4 [Cu(NH3)2]+ + N2O + H2O + 4 H+ + 8 NH3 + H2O
It reacts with zinc oxide or zinc carbonate to generate hydroxylamine complex Zn(ONH3)Cl2.
Sodium nitrite and sodium metabisulfite react in water, acidify with sulfuric acid, add a certain amount of acetone, and neutralize with liquid caustic soda. The acetone oxime is distilled out, and the acetone oxime is reacted with a certain proportion of hydrochloric acid to generate hydroxylamine hydrochloride and acetone. Hydrolysis of nitromethane and hydrochloric acid produces hydroxylamine hydrochloride.
Hydroxylamine Hydrochloride Uses
- Hydroxylamine hydrochloride is an important organic chemical intermediate, mainly used in the preparation of oximes in organic synthesis reactions, such as the intermediate of trimoxazole in the pharmaceutical industry, and the preparation of isatin intermediate in the synthetic dye industry.
- In medication, it is additionally made use of to create cotrimoxazole, danazol, ethinyl estradiol, norethisterone, methyl testosterone, hydroxyurea, chlordiazepoxide, etc. In the artificial rubber industry, it is utilized as a non-coloring short-term quit.
- Because hydroxylamine hydrochloride has a good decreasing impact, it is frequently made use of as a lowering representative in industry, such as in the oil industry, it can be used as an antioxidant as well as antioxidant for fatty acids and soaps.
- Not natural evaluation of decreasing agents, complexing representatives, electroanalytical depolarizers, anti-oxidants for fats as well as soaps, analysis of formaldehyde, camphor and also glucose, and so on, organic analysis of aldehydes and also ketones, trace evaluation of sulfonic acids, determination of magnesium in steel, Prep work of oximes by natural synthesis. Color photo processing. driver. swelling representative. Copolymerization prevention.
