Main properties and applications of sodium hypochlorite

Sodium hypochlorite is mainly used in bleaching, industrial wastewater treatment, papermaking, textile, pharmaceuticals, fine chemicals, sanitary disinfection and many other fields.

Sodium hypochlorite, the hypochlorite of sodium. Sodium hypochlorite reacts with carbon dioxide to produce hypochlorous acid, which is the active ingredient in bleach. It is white and extremely unstable solid, and is easy to explode when mixed with organic materials or reducing agents. Aqueous solution alkaline, and slowly decomposed into NaCl, NaClO₃ and O₂, rapid decomposition by heat and light, strong oxidizing. Sodium hypochlorite is mainly used in bleaching, industrial wastewater treatment, papermaking, textiles, pharmaceuticals, fine chemicals, sanitation and disinfection and many other fields, specifically:

1, used for pulp, textiles (such as cloth, towels, sweatshirts, etc.), chemical fiber and starch bleaching;

2、Soap-making industry used as bleaching agent for fats and oils;

3, chemical industry for the production of hydrazine hydrate, monochloramine, dichloramine;

4、Used in the manufacture of cobalt, nickel chlorination agent;

5、Used as water purifier, bactericide and disinfectant in water treatment;

6、Used in the dye industry for the manufacture of sulfur blue;

7、Organic industry for the manufacture of chloropicrin, calcium carbide hydration system acetylene cleaning agent;

8、Agriculture and animal husbandry used as vegetables, fruits, feedlots and barns and other disinfectants and deodorizers;

9, food-grade sodium hypochlorite is used for the disinfection of beverage water, fruits and vegetables, food manufacturing equipment, utensils sterilization and disinfection, but can not be used for sesame as raw material for the food production process.

Sodium hypochlorite is a strong oxidizing agent, used as bleaching agent, oxidizing agent and water purifying agent for paper, textile, light industry, etc., with bleaching, sterilization, disinfection. It is used for water purification, as well as disinfectant, pulp bleaching, etc. It is used to make chloramine in the pharmaceutical industry.
