Read： 510 Time：11months ago Source：Transform the World with Simplicity

Chlorine dioxide (ClO2) is a strong oxidant, with broad-spectrum, high efficiency, non-toxic characteristics, is widely used in the field of chemical production raw materials. This article will detail the nature and use of chlorine dioxide.

1. The properties of chlorine dioxide

1. Physical properties
chlorine dioxide is a yellow-green gas with a pungent odor. It is easily soluble in water and has a high solubility in water. The aqueous solution of chlorine dioxide is yellow-green and has a strong oxidizing ability.

2. chemical properties
chlorine dioxide has a strong oxidation, its oxidation potential is higher than chlorine and hypochlorous acid, so it can oxidize many organic and inorganic substances. Chlorine dioxide has a higher oxidizing power under acidic conditions, but it can also exhibit some oxidation under alkaline conditions.

2. the use of chlorine dioxide

1.
of chemical raw materials chlorine dioxide as a strong oxidant, is widely used as chemical raw materials. It can be used to produce many important chemical products, such as chlorinated hydrocarbons, chlorinated fatty acids, chlorohydrins, etc. In addition, chlorine dioxide can also be used to produce hydrogen peroxide, oxygen, etc.

2. Water treatment agent
Chlorine dioxide has a wide range of applications in the field of water treatment. It can effectively kill bacteria, viruses and algae in the water, while removing the color and odor in the water. Compared with traditional chlorine disinfection, chlorine dioxide disinfection does not produce harmful by-products, so it is widely used in the treatment of drinking water, industrial water and swimming pool water.

3. bleach
chlorine dioxide has a strong bleaching effect, can be used for paper, textiles, chemical fiber and other materials bleaching. In contrast to conventional chlorine bleaching, chlorine dioxide bleaching does not damage fibers and does not produce toxic and harmful by-products.

4. Food additive
Chlorine dioxide can be used as a food additive for food preservation and preservation. It can effectively kill bacteria and mold in food and extend the shelf life of food. At the same time, chlorine dioxide also has an antioxidant effect, which can maintain the nutritional content and color of food.

In short, chlorine dioxide has a wide range of applications in the field of chemical production raw materials, and can be used to produce chemical raw materials, water treatment agents, bleaching agents and food additives. Because of its strong oxidation and broad-spectrum bactericidal ability, chlorine dioxide will play a more important role in the future chemical production.
