Ammonium bisulfite for medicine

Medical ammonium bisulfite is white orthorhombic prisms, and medical ammonium bisulfite has the odor of sulfur dioxide. It is easily oxidized in the air and decomposes into sulfur dioxide when heated.

MedicalAmmonium BisulfiteThe density is 2.03g/cm3. Melting point 150°C (sublimation in nitrogen). It is soluble in water and is only stable in solution. It is prepared by absorbing and contacting sulfur dioxide from the raw material gas or sulfur dioxide in the tail gas in the production of sulfuric acid produced by the ammonia water absorption contact method, and then concentrated, cooled, crystallized and centrifuged. It can be used as a raw material for manufacturing 100% sulfur dioxide, caprolactam, synthetic tanning, pulp cooking agent, etc.

Ammonium bisulfite for industrial use is a yellow-brown solution. The sum of ammonium bisulfite and ammonium bisulfite is greater than or equal to 54.0%, with the odor of sulfur dioxide. It is easily oxidized in the air. Decomposes into sulfur dioxide when heated. It can be used to synthesize dye intermediates, surfactants, pesticides, herbicides, reducing agents in the pharmaceutical industry, and to protect the development process of the photosensitive industry.

Ammonium bisulfite solution is obtained by absorbing the tail gas from ammonia water production. It is also used as a raw material for the manufacture of liquid sulfur dioxide, sodium sulfite and sodium hydroxide, and as a reducing agent in the pharmaceutical industry.
