[Chemical Knowledge]:What are the upstream raw materials for sodium chlorite? What are the downstream products?

Sodium chlorite is an important chemical raw material, which is widely used in water treatment, pulp bleaching, food disinfection and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of sodium chlorite mainly include the following categories:

upstream products:

1. Caustic soda: Caustic soda is one of the main raw materials for the production of sodium chlorite, which reacts with chlorine through a chemical reaction to generate sodium chlorite.

2. Chlorine: Chlorine is another important raw material for the production of sodium chlorite, which reacts with caustic soda to produce sodium chlorite and sodium chloride.

Downstream products:

1. Chlorine dioxide: Sodium chlorite can be used as a chlorine dioxide generator and react with water to generate chlorine dioxide. Chlorine dioxide is a broad-spectrum and efficient disinfectant. It is widely used in the disinfection treatment of drinking water, industrial water, medical water and other fields.

2. Pulp bleach: Sodium chlorite can be used as a pulp bleach to react with lignin, pigment and other impurities in the pulp to improve the whiteness and purity of the pulp and improve the quality of the paper.

3. chemical reagents: sodium chlorite can be used as a raw material for some chemical reagents, such as for the preparation of chlorous acid, barium chlorite, etc.

In short, sodium chlorite plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are widely used in various fields, such as water treatment, papermaking, medical treatment, chemical reagents, etc.
