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

Properties of sodium perborate

Sodium perborate (sodium Perborate) is an inorganic compound, common in the form of tetrahydrate and monohydrate. Its chemical formula is NaBO3 · 4H2O and NaBO3 · H2O. Sodium perborate in water can be slowly decomposed to generate hydrogen peroxide (H2O2) and boric acid (H3BO3), with good oxidation. It is a white odorless powder that releases oxygen when dissolved in water, showing good bleaching and sterilization effects. The solubility is different at different temperatures, and the solubility is better at higher temperatures.

Use of sodium perborate

sodium perborate is widely used in many fields. Its main uses include the following:

1. detergents and bleaches: As an oxidizing bleaching agent, sodium perborate is often used in laundry powders and liquid laundry detergents to effectively remove stains and whiten fabrics.
2. Disinfectant: Because of the strong oxidizing nature of the hydrogen peroxide released by it, sodium perborate is used as a disinfectant in medical and household cleaning, which can kill bacteria and viruses.
3. teeth whitening: Sodium perborate is also used in toothpaste and teeth whitening products to bleach and remove plaque.
4. Chemical reagent: In the chemical industry, sodium perborate can be used as an oxidant and bleaching agent in various chemical reactions.

Upstream and downstream raw materials of sodium perborate

the main raw materials for the production of sodium perborate include boric acid (H3BO3) and hydrogen peroxide (H2O2). Among them, boric acid is a common industrial chemical, mainly extracted from borax ore, while hydrogen peroxide is an important industrial chemical, produced by electrolysis or steam. The supply stability and price fluctuation of upstream raw materials directly affect the production cost and market price of sodium perborate.

Production process of sodium perborate

the production process of sodium perborate consists of two main steps:

1. reaction steps: First, mix boric acid and hydrogen peroxide, and react under appropriate temperature and pH conditions to generate a perboric acid solution.
2. Crystallization step the perboric acid solution is then cooled and subjected to a crystallization treatment to isolate the sodium perborate solid. Finally, the pure sodium perborate product is obtained by filtration, washing and drying steps.

Storage method of sodium perborate

sodium perborate is oxidizing and deliquescent, so special attention is required when storing:

1. drying and sealing: Sodium perborate should be stored in a dry, cool, well-ventilated place, and use a sealed container to prevent its moisture absorption and decomposition.
2. Keep away from light: Since light may accelerate the decomposition of sodium perborate, it needs to be stored in the dark and avoid direct sunlight.
3. Isolation of flammable materials: As an oxidant, sodium perborate should be kept away from flammable and reducing substances to prevent chemical reactions or fires.
4. Temperature control the storage temperature should be controlled within a suitable range to avoid high temperature environments to reduce its decomposition rate and maintain stability.

Market Analysis and Development Prospects

the demand for sodium perborate in the market is mainly driven by the market for detergent and disinfection products. With the improvement of people's requirements for hygiene and health, the demand for household cleaning products has steadily increased, which has provided strong support for the market of sodium perborate. The increasingly stringent environmental regulations have also prompted companies to seek more environmentally friendly and more efficient bleaching and disinfection solutions. Sodium perborate, as a relatively environmentally friendly oxidant, is expected to gain more applications in the market.

The sodium perborate market also faces some challenges. For example, competition from alternatives such as hydrogen peroxide, and possible cost pressures from fluctuations in upstream feedstock prices. Technological innovation and product upgrading are also aspects that enterprises need to pay continuous attention to in order to maintain market competitiveness.

Conclusion

as an important chemical product, sodium perborate is widely used in detergent, disinfectant, tooth whitening products and other fields because of its good bleaching and sterilization effect. Its production relies on upstream raw materials such as boric acid and hydrogen peroxide, and the production process includes two main steps: reaction and crystallization. Care shall be taken during storage for drying, sealing, protection from light and temperature control. With the growth of market demand and the improvement of environmental protection requirements, sodium perborate has a broad development prospect, but it also needs to deal with the challenges of market competition and cost fluctuation. Overall, sodium perborate will continue to play an important role in the future cleaning and disinfection market.
