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

Properties of sodium percarbonate

Sodium percarbonate (Percarbonate) is a white amorphous particle with stable chemical properties. It dissolves easily in water, releasing hydrogen peroxide and sodium carbonate during the dissolution process. Since hydrogen peroxide is a strong oxidizing agent, sodium percarbonate can exhibit strong oxidizing properties after being dissolved in water, thereby giving it excellent bleaching and disinfection properties. Its chemical formula is 2Na CO₂ · 3H O₂, showing its dual nature of sodium carbonate and hydrogen peroxide.

Sodium Peroxide Use

Sodium peroxycarbonate is widely used in many fields, most notably in detergents and cleaners. Due to the strong oxidation and bleaching ability of hydrogen peroxide produced by its decomposition, sodium percarbonate is widely used in household and industrial cleaning products for bleaching clothes, removing stubborn stains and disinfecting and sterilizing. Sodium peroxycarbonate is also used as a detergent and bleach in the food industry, as well as a disinfectant for medical devices and environmental hygiene. It is also used in the paper industry to bleach pulp and has applications in soil improvement and water treatment.

Upstream raw materials

The main raw materials for the production of sodium percarbonate include sodium carbonate (Na₂ CO₂) and hydrogen peroxide (H₂ O₂). Sodium carbonate is a common industrial chemical, widely used in glass making, paper making, detergent and chemical industries. Hydrogen peroxide is a strong oxidant, widely used in disinfection, bleaching and chemical synthesis. In the production of sodium peroxycarbonate, sodium carbonate is usually dissolved in a hydrogen peroxide solution and reacted to produce sodium peroxycarbonate by controlling the temperature and concentration.

Downstream Products

The downstream products of sodium percarbonate mainly include various types of detergents and bleaches. For example, in detergents, it acts as the main bleaching ingredient, working together with other active ingredients and auxiliaries to enhance the washing effect. Sodium peroxycarbonate is also used in household cleaning products, such as floor cleaners, toilet cleaners, etc., for stain removal and disinfection. Since its decomposition products are non-toxic and environmentally friendly, sodium peroxide is also used in ecological cleaning products.

storage method

Sodium peroxycarbonate has a certain chemical activity, so its storage method requires special attention. Sodium peroxycarbonate should be stored in a dry, cool environment to avoid moisture and high temperature to prevent its decomposition. Contact with acidic substances and reducing agents should be avoided to prevent chemical reactions. Sodium peroxycarbonate should be stored in a closed container to prevent it from absorbing moisture from the air. For industrial storage, the relevant safety regulations should be met, the warehouse should be well ventilated, and the necessary fire fighting equipment should be equipped.

Safety and environmental protection

Sodium peroxycarbonate needs to be safe during use and handling. The hydrogen peroxide produced by its decomposition is a strong oxidizing agent, which is corrosive and may cause skin and eye irritation. Therefore, protective gloves and goggles should be worn during operation to avoid direct contact. Because sodium percarbonate is oxidizing, it should be avoided to be mixed with flammable substances and reducing agents. In terms of environmental protection, the decomposition products of sodium percarbonate are mainly water and sodium carbonate, which are environmentally friendly and will not produce toxic by-products, but the oxygen released may increase the risk of fire.

Market Prospects

With the improvement of people's requirements for environmental protection and health, the demand for sodium percarbonate in the market is on the rise because of its non-toxic and environmental protection characteristics. Especially in the field of detergents and cleaning products, consumers are increasingly inclined to choose products that are phosphorus-free, non-toxic and environmentally friendly, which provides a broad market space for sodium percarbonate. In the food industry, health care and environmental protection, the application of sodium percarbonate is gradually expanding. Therefore, the future market prospects of sodium peroxycarbonate are generally optimistic.

Production process improvement

At present, there is still room for improvement in the production process of sodium percarbonate. Improving production efficiency, reducing energy consumption and reducing by-products are the key directions of future research. For example, the yield and purity of sodium peroxycarbonate can be improved by optimizing the reaction conditions and using efficient catalysts. The development of green production processes to reduce the impact on the environment is also an important issue in the future. With the progress of science and technology, it is expected that more efficient and environmentally friendly production processes will be developed to further promote the development of sodium percarbonate industry.

Summary

As an important chemical product, sodium percarbonate has excellent bleaching and disinfection properties, and is widely used in detergents, cleaners, food industry and medical and health fields. Its production raw materials are mainly sodium carbonate and hydrogen peroxide, through reasonable storage and safety measures, can effectively play its role. With the enhancement of environmental awareness and technological progress, the market prospect of sodium percarbonate is broad, and it is expected to be applied and developed in more fields in the future.
