Ammonium bisulfite is an inorganic compound with the molecular formula nh4hso3. The white rhomboid prism is a low-toxic compound. The concentrate is slightly irritating to the skin, but short-term contact will not cause damage. After contact with the solution, rinse with water for a while. The product itself has no fire and explosion hazard. In case of fire, you can extinguish it with water. It can be used as preservative, reducing agent, sulfur dioxide, sodium bisulfite, 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.

It can react with acids and bases. It is easily oxidized in the air. When heated, it decomposes and releases sulfur dioxide. It is easily soluble in water and sublimates at 150°C. It is reductive and will slowly oxidize to sulfate in the air. Ammonium bisulfite solution has the odor of sulfur dioxide, which will decompose and release sulfur dioxide when it encounters acid.

It can be used as preservative, reducing agent, sulfur dioxide, sodium bisulfite, etc.

In the drilling industry, adding ammonium bisulfite and crystalline Fe3O4 (as a catalyst) to drilling mud containing montmorillonite can effectively remove dissolved oxygen in the mud and prevent well pipe corrosion.

In addition, ammonium bisulfite can be used to produce pure liquid sulfur dioxide, sodium bisulfite, sodium bisulfite, some dyes and drugs; it is a raw material for caprolactam production in synthetic fiber production; it is used in pulp and paper industries Pulping and bleaching.

In the field of water treatment, it can be used as a deoxidizer for boiler water, drilling mud and closed-circuit cooling water to prevent dissolved oxygen from corroding equipment. Especially suitable for small and medium-sized low-pressure boilers.

Used as a reducing agent in the pharmaceutical industry.
