Chlor-alkali chemical industry and ethylene glycol are two common chemical substances in the chemical industry, and they have many differences in the production and application process. This article will introduce the difference between the two in terms of scale, production, use and environmental impact.

from the scale point of view, chlor-alkali chemical industry is a huge industrial system, including chlor-alkali preparation, chlorination industry and alkali industry three categories of industries. It mainly uses sodium chlorate as raw material to produce sodium hydroxide and chlorine by electrolysis, and then through a series of chemical reactions to obtain chlor-alkali products. Ethylene glycol is a single organic compound and is produced on a relatively small scale.

in the production process, chlor-alkali chemical industry needs high temperature and high pressure equipment and complex process, the production process is more complex, but also involves some dangerous substances handling and safety issues. The production of ethylene glycol is relatively simple, mainly obtained by ethylene and water synthesis, and the production process is relatively stable.

in the use of chlor-alkali chemical products are widely used in metallurgy, building materials, electronics, textiles, pharmaceuticals and many other fields. For example, sodium hydroxide is used as a neutralizing agent, leaching agent, mineral replenishment agent, etc., and chlorine gas has a wide range of applications in water treatment, disinfection and as a chlorine agent. Ethylene glycol is mainly used to prepare organic compounds such as esters, ethers, polyethers and resins, and is widely used in pharmaceutical, plastic, textile, ink and other industries.

environmental impact, chlor-alkali chemical production process will produce a large amount of chlorine, hydrogen chloride and other harmful gases, causing certain pollution to the environment. The production of ethylene glycol is relatively environmentally friendly and has less impact on the environment.

To sum up, there are obvious differences between chlor-alkali chemical industry and ethylene glycol in terms of scale, production, use and environmental impact. Understanding these differences will help us to better understand and use these two chemicals, promote the development of the chemical industry and environmental protection.
