| Application | mainly used in the preparation of caprolactam and used as pharmaceutical, pesticide intermediates hydroxylamine sulfate, also known as hydroxylamine sulfate, hydrazine sulfate. Its derivatives, oxime or hydroxamic acid derivatives, can be used in the production of insecticides such as methomyl, aldicarb and methomyl, as well as fungicides and herbicides. Hydroxylamine sulfate is a reducing agent, developer and rubber vulcanizing agent, is an important raw material for the synthesis of caprolactam, also used in the production of isoxazole derivatives, sulfanilamide drugs and vitamin B5, vitamin B12, it can also be used for polymer synthesis and chemical analysis. used as a reducing agent, a developer, and a rubber vulcanizing agent. This product is an important raw material for the synthesis of caprolactam. Is also a pharmaceutical, pesticide intermediates, for the production of a series of isoxazole derivatives, sulfa drugs and vitamin B6, B12. Derivatives oxime or hydroxamic acid derivatives can be used to produce pesticides, insecticides, fungicides and herbicides. It can also be used for the purification of polymer synthesis raw materials and compounds, polymerization catalysts and chemical analysis reagents. used as analysis reagent, reducing agent, also used in organic synthesis inorganic analysis reducing agent, can reduce the compound of gold, silver and Mercury into monomer elements, and Fe3, Cu2, v5 is reduced to low-valent compounds, determination of selenium, biological and biochemical studies, photographic developer, manufacture of oxime, Catalyst, swelling agent, polymerization inhibitor of copolymerization reaction, leather hair removal, etc. |
| 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. |
