Chemical properties

Use

●  It is mainly used in the preparation of caprolactam and as an intermediate of medicine and pesticide

●  Hydroxylamine sulfate is also known as hydroxylamine sulfate and urethane sulfate. Its derivatives oxime or hydroxamic acid derivatives can be used to produce insecticides such as methomyl, aldicarb and thiodicarb, as well as fungicides and herbicides. Hydroxylamine sulfate is a reducing agent, developer and rubber vulcanizing agent. It is an important raw material for the synthesis of caprolactam. It is also used in the production of isoxazole derivatives, sulfa drugs, vitamin B5, and vitamin B12. It can also be used in polymer synthesis and chemistry. analyze.

●  Used as reducing agent, developer and rubber vulcanizing agent. This product is an important raw material for the synthesis of caprolactam. It is also an intermediate of medicine and pesticide, used in the production of a series of isoxazole derivatives, sulfonamides and vitamins B6 and B12. Derivatives Oxime or hydroxamic acid derivatives can be used to produce pesticides, fungicides and herbicides. It can also be used in the purification of polymer synthesis raw materials and compounds, polymerization catalysts and chemical analysis reagents, etc.

●  Used as analytical reagent, reducing agent, also used in organic synthesis

●  Inorganic analytical reducing agent, which can reduce gold, silver and mercury compounds to single elements, and reduce Fe3+, Cu2+, V5+ to low-priced compounds, determine selenium, biological and biochemical research, photographic developer, manufacture oxime, catalyst, Swelling agent, copolymerization inhibitor, leather depilation, etc.

Production method

●  1. React methyl ethyl ketone with sulfuric acid and ammonia to produce methyl ethyl ketone oxime, then react with sulfuric acid and hydrolyze to produce hydroxylamine sulfate (crystalline form), methyl ethyl ketone and ammonium sulfate as by-products. 2. React by mixing sodium nitrite and ammonium bisulfite, feed sulfur dioxide at low temperature to absorb the reactant to obtain hydroxylamine disulfonate, and then hydrolyze to obtain hydroxylamine sulfate. 3. Hydroxylamine sulfate can also be prepared by reacting sulfuric acid with nitrohydrocarbons.

●  There are two methods for the synthesis of hydroxylamine sulfate.
React methyl ethyl ketone, sulfuric acid and ammonia to generate methyl ethyl ketone oxime, then react with sulfuric acid and hydrolyze to obtain hydroxylamine sulfate.
Sodium nitrite and ammonium bisulfite are mixed, and sulfur dioxide is introduced at 0-5°C to absorb and react to obtain hydroxylamine disulfonate, which is then hydrolyzed into hydroxylamine sulfate.
