[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of sodium percarbonate, what are the properties of sodium percarbonate

Sodium percarbonate properties

Sodium percarbonate (Sodium Percarbonate), the chemical formula of 2Na₂ CObasis · 3H₂ O₂, is a white, odorless crystalline powder. It is a complex of sodium carbonate and hydrogen peroxide, often referred to as solid hydrogen peroxide. When sodium percarbonate is dissolved in water, it will decompose to form sodium carbonate and hydrogen peroxide, so it has strong oxidation and alkalinity. Its decomposition temperature is about 50°C, it can remain stable at higher temperatures, and it has good biodegradability and will not pollute the environment.

Sodium percarbonate uses

Sodium percarbonate is widely used in detergents, cleaning agents, bleaching agents and disinfectants because of its strong oxidation and good bleaching effect. In household cleaning, sodium percarbonate is often used in washing powder and detergent, can effectively remove stains and sterilization. In industry, sodium percarbonate is used for the bleaching of textiles and for the bleaching of pulp. Sodium percarbonate can also be used in tooth whitening products, water treatment and soil improvement in agriculture. The environmentally friendly nature of sodium percarbonate makes it a good alternative to traditional bleaching agents, especially in industries with high environmental requirements.

Sodium percarbonate upstream and downstream raw materials

The main raw materials for the production of sodium percarbonate are sodium carbonate and hydrogen peroxide. Sodium carbonate (Na₂ CO), commonly known as soda ash or soda, is an important chemical raw material, mainly derived from natural alkali ore or prepared by ammonia alkali method. Hydrogen peroxide (H₂ O₂), a colorless liquid with strong oxidizing properties, is mainly produced by the anthraquinone process. In the production process, sodium carbonate and hydrogen peroxide react at a certain temperature and pressure to form sodium percarbonate. The production process also requires the addition of stabilizers to prevent rapid decomposition of hydrogen peroxide.

Sodium Percarbonate Production Process

The production process of sodium percarbonate mainly includes drying method and spray granulation method. The drying method is to mix sodium carbonate with hydrogen peroxide and then dry at low temperature to form sodium percarbonate crystals. The rule of spray granulation is to spray dry sodium carbonate solution and hydrogen peroxide solution through spray drying equipment at high temperature to form granular sodium percarbonate. Compared with the drying method, the spray granulation method can produce sodium percarbonate products with uniform particles and good solubility, so it is more widely used in industrial production.

Sodium Percarbonate Storage Method

Sodium percarbonate has a high activity, so you need to pay attention to the following points when storing: Sodium percarbonate should be stored in a dry, well-ventilated warehouse to avoid moisture and direct sunlight. Sodium percarbonate should be stored separately from flammable materials, reducing agents and acid chemicals to avoid reaction. Again, the temperature of the storage environment should be kept low to prevent the sodium percarbonate from decomposing. Sodium percarbonate should be packaged in a sealed container to prevent moisture absorption and oxidation and extend its service life.

Sodium Percarbonate Market Prospects

With the improvement of people's environmental awareness and the increasing demand for green chemicals, the market demand for sodium percarbonate is growing. Especially in the field of detergents, cleaners and disinfectants, sodium percarbonate is widely used because of its good bleaching and bactericidal effect. The bleaching of textiles and pulp is also gradually replacing traditional bleaching agents with sodium percarbonate to reduce environmental pollution. In the future, with the improvement of sodium percarbonate production process and the expansion of application fields, its market prospect will be broader.

ENVIRONMENTAL PROPERTIES OF SODIUM CARBONATE

As an environmentally friendly oxidant, sodium percarbonate is decomposed into sodium carbonate and water, which is harmless to the environment. Compared with traditional chlorine bleach, sodium percarbonate does not produce toxic by-products such as dioxins and chloroform during use. Therefore, the use of sodium percarbonate in environmentally friendly detergents and cleaners is increasing. The biodegradability of sodium percarbonate makes its application in agriculture and water treatment also has significant environmental advantages.

Sodium Percarbonate Safety

Although sodium percarbonate has good environmental protection characteristics, it is still necessary to pay attention to safety during use. Sodium percarbonate is highly oxidizing and may cause irritation or burns on contact with the skin or eyes, so protective gloves and goggles should be worn during operation. Sodium percarbonate is easy to decompose and release oxygen at high temperature, and there is a certain fire risk. Therefore, sodium percarbonate should be stored in a cool, dry, well-ventilated place, and away from fire and heat sources. Sodium percarbonate should avoid contact with reducing agents, acids and inflammables to prevent chemical reactions.

Conclusion

As an important chemical raw material, sodium percarbonate is widely used in detergent, cleaning agent, bleaching agent and disinfectant because of its strong oxidation, good bleaching effect and environmental protection characteristics. Its production raw materials are mainly sodium carbonate and hydrogen peroxide, and the production process includes drying method and spray granulation method. The storage of sodium percarbonate requires attention to moisture-proof, heat-proof, fire-proof and other measures. With the improvement of environmental awareness, the market demand for sodium percarbonate is growing, and its future application prospects are broad. Pay attention to safety and take necessary protective measures during use.
