colorless or white crystals. The melting point was about 170 °c (decomposition). Boiling point 56.5 °c. Density 1.204g/cm3. Soluble in cold water, ethanol and methanol. Easy to absorb moisture. The nature of hydroxylamine is very unstable, and it is gradually decomposed at room temperature, and it will be explosive at higher temperature. Therefore, it is usually made into relatively stable sulfate and hydrochloride. Among them, hydroxylamine sulfate is the most commonly used.
This product is used as a reducing agent, developer and rubber vulcanizing agent, is an important raw material for the synthesis of caprolactam, is also an intermediate of medicine, pesticide, used in the production of a series of isoxazole derivatives, sulfa drugs and vitamins B6, B,z. In addition, its oxime or hydroxamic acid derivatives can be used for the production of pesticides, fungicides and herbicides. It can also be used for the purification of polymer synthesis raw materials and compounds, polymerization catalysts and reagents.

production method | 1. With methyl ethyl ketone and sulfuric acid and ammonia reaction to produce methyl ethyl ketone oxime, and then with sulfuric acid reaction, through hydrolysis of hydroxylamine sulfate (crystalline) and methyl ethyl ketone and ammonium sulfate by-products. 2. The reaction is carried out by mixing sodium nitrite and ammonium bisulfite, and sulfur dioxide is introduced to absorb the reactant to obtain hydroxylamine disulfonate at low temperature, and then hydrolysis is carried out to obtain hydroxylamine sulfate. Hydroxylamine sulfate can also be obtained by the reaction of sulfuric acid with Nitro hydrocarbon. There are two synthetic methods of hydroxylamine sulfate. Methyl Ethyl Ketone and sulfuric acid are reacted with ammonia to form methyl ethyl ketone oxime, which is then reacted with sulfuric acid to hydrolyze hydroxylamine sulfate. Sodium nitrite and ammonium bisulfite are mixed, and sulfur dioxide is introduced at 0~5 ℃ to absorb and react to obtain hydroxylamine disulfonate, which is hydrolyzed to hydroxylamine sulfate. |
