The nature and use
of zinc oxide in the field of chemical production raw materials
1. Introduction

Zinc oxide is a widely used chemical raw material. Because of its unique physical and chemical properties, it has a wide range of applications in many fields. Especially in the production of chemical products, zinc oxide plays an important role. This paper will discuss in detail the properties of zinc oxide and its application in the field of chemical production raw materials.

2. The properties of zinc oxide

1. Physical properties: Zinc oxide is a white or yellowish powder, odorless and tasteless. It is insoluble in water, but can be dissolved in acidic solutions. The melting point of zinc oxide is high, about 1975 ℃.
2. chemical properties: zinc oxide has amphoteric, can react with acid, can also react with alkali. In addition, it also has good oxidation resistance and thermal stability.

3. zinc oxide in the chemical production of raw materials in the field of application

1 catalyst: zinc oxide can be used as a catalyst for many chemical reactions, such as ester exchange reaction, dehydrogenation reaction. Due to its unique catalytic properties, zinc oxide plays an important role in the production of many chemical products.
2. Preservative: Zinc oxide has antibacterial and anti-mildew properties, so it is often used as a preservative in chemicals. It can effectively extend the service life of chemicals and improve the stability of products.
3. Antioxidant: Because zinc oxide has good oxidation resistance, it can be used as an antioxidant in some chemicals to improve the oxidation resistance of the product.
4. Pigments and fillers: Zinc oxide has a certain hiding power and tinting power, so it is often used as a pigment and filler. In the production of chemical products, it can improve the appearance quality and stability of the product.

4. conclusion

zinc oxide as an important chemical raw material, has a wide range of applications in the field of chemical production raw materials. Due to its unique physical and chemical properties, zinc oxide plays an important role in the fields of catalysts, preservatives, antioxidants and pigments. With the continuous development of science and technology, zinc oxide will be more widely used in chemical production and make greater contributions to the development of the chemical industry.
