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

Nitrogen is a colorless, odorless, non-reactive gas, accounting for 78% of the proportion in the atmosphere. Because of its unique physical and chemical properties, nitrogen has a wide range of applications in the field of chemical production raw materials. This article will discuss in detail the nature of nitrogen and its use in the field of chemical production raw materials.

2. the nature of nitrogen

1. physical properties: nitrogen is colorless, tasteless gas, density is slightly smaller than air, slightly soluble in water. At normal temperature and pressure, nitrogen is a very stable gas, not easy to react with other substances.
2. chemical properties: chemical properties of nitrogen is relatively inert, usually not easy to react with other elements or compounds. However, nitrogen can react with certain elements (such as hydrogen) at high temperatures, high pressures, or in the presence of catalysts.

3. the use of nitrogen in the field of chemical production of raw materials in the field of

1 ammonia synthesis: nitrogen and hydrogen in high temperature, high pressure and the role of the catalyst under the reaction of ammonia. Ammonia is an important raw material for nitrogen fertilizer, nitric acid, explosives and other chemicals.
2. Production of nitric acid: Nitrogen reacts with oxygen at high temperatures to produce nitrogen oxides, which in turn reacts with water to produce nitric acid. Nitric acid is widely used in the production of chemical fertilizers, explosives, dyes and other chemicals.
3. Manufacture of nitrogen fertilizer: After nitrogen reacts with hydrogen to generate ammonia, it can be further made into various nitrogen fertilizers, such as urea, ammonium nitrate, etc.
4. Production of plastics and rubber: Nitrogen can be used as a protective gas to prevent oxidation of materials during polymerization and improve product quality.
5. Preparation of electronic gas: Nitrogen can be used as a raw material gas, through a certain process to prepare high-purity electronic gas, such as silicon nitride, boron nitride, etc., widely used in semiconductors, display panels and other electronic industries.

4. conclusion

nitrogen has a wide range of applications in the field of chemical production raw materials, mainly due to its stable physical and chemical properties. Through in-depth understanding and research on nitrogen, we can make better use of this resource and contribute to the development of chemical production. At the same time, with the continuous progress of science and technology, we believe that the application field of nitrogen will continue to expand, bringing more benefits to human society.

5. Outlook

With the continuous development of chemical production technology and the improvement of environmental protection requirements, the application of nitrogen in the field of chemical production raw materials will be more extensive. In the future, we need to further study and explore new properties and new uses of nitrogen to meet the growing demand for chemical production. At the same time, we also need to pay attention to the environmental problems that may be caused by the use of nitrogen, take measures to reduce energy consumption and emissions, and realize the green and sustainable development of chemical production.

In short, nitrogen has an important role and broad application prospects in the field of chemical production raw materials. Through continuous in-depth research and practice, we are expected to make better use of nitrogen resources, promote innovation and development in the field of chemical production, and contribute to the prosperity and progress of human society.
