The nature and use
of industrial liquid chlorine
1. Introduction

Industrial liquid chlorine is an important raw material for the production of chemical products, widely used in various fields. This article will introduce the properties and uses of industrial liquid chlorine in detail, so that readers can better understand and apply this important chemical raw material.

2. industrial properties of liquid chlorine

1. physical properties of

industrial liquid chlorine for yellow green transparent liquid, with pungent odor. Its boiling point is -34.6 ℃, freezing point is -101.5 ℃, relative density is 1.47. The vapor pressure of liquid chlorine increases with the increase of temperature and has a higher volatility.

2. chemical properties

liquid chlorine has strong oxidation, can react with many substances. For example, liquid chlorine reacts with metals to produce the corresponding metal chlorides and reacts with non-metals to produce the corresponding non-metal chlorides. In addition, liquid chlorine can also react with water to generate hydrochloric acid and hypochlorous acid, and react with alkali to generate the corresponding chloride and hypochlorite.

3. industrial use of liquid chlorine

1. chemical production

industrial use of liquid chlorine in chemical production has a wide range of applications, mainly for the production of various chlorides. For example, liquid chlorine reacts with methane to form methyl chloride, which in turn can produce a series of chlorides such as dichloromethane, trichloromethane and carbon tetrachloride. In addition, liquid chlorine can also be used to produce vinyl chloride, chlorobenzene and other important organic chemical raw materials.

2. water treatment

liquid chlorine, as an effective disinfectant, is widely used in the field of water treatment. After adding liquid chlorine to the water, it can quickly kill bacteria, viruses, algae and other microorganisms in the water to ensure the safety of drinking water.

3. Paper industry

In the papermaking process, liquid chlorine can be used to bleach pulp and improve the whiteness and quality of paper. At the same time, liquid chlorine can also be used to treat organic substances in papermaking wastewater to reduce environmental pollution.

4. pharmaceutical manufacturing

liquid chlorine can be used for the synthesis of a variety of drugs, such as antibacterial drugs, anti-tumor drugs. In addition, liquid chlorine can also be used in the production of medical equipment and disinfection supplies.

5. Agricultural

In the agricultural field, liquid chlorine can be used for soil disinfection, pest control, etc. At the same time, liquid chlorine can also be used to prepare pesticides and fertilizers to improve crop yield and quality.

4. conclusion

In short, industrial liquid chlorine has a wide range of applications in the field of chemical production raw materials, and has played an important role in promoting the development of various industries. Understanding and mastering the properties and uses of liquid chlorine will help to better apply this important chemical raw material and improve production efficiency and product quality.
