Sodium hydrosulfite is a pulp bleaching agent in the paper production process, and it is expected that the demand for the production of this chemical will increase until 2024. This substance is produced in the industry by reducing sulfur dioxide and cannot be stored for a long time because it decomposes quickly.
What is Sodium Hydro Sulfite?
A crystalline solid with a white to light yellow color, which is a type of salt soluble in water. This compound also has the ability to dissolve in alcohols and ethers. It has the chemical formula NaHS and is a very efficient material in the paper production sector. And it is textile. Sodium hydrosulfite is also known as sodium dithionite.
This compound is stable when it is not in contact with air, but it decomposes quickly in hot water and acidic solution. This substance is in contact with It heats up by itself with moisture and water.
