Ethylene glycol is a chemical substance. The following is an introduction to its properties, uses, production methods, and safety information:

Properties:
Physical properties: It is a colorless, viscous liquid with a sweet taste and is almost odorless at room temperature.
Chemical properties: It is a hydrophilic substance that can mix with water and other organic solvents. It can be oxidized into a series of compounds such as aldehydes, acids, and esters.

Uses:
Industrial uses: Used in the production of synthetic polymers such as polyester fibers and polyethers, and also serves as a coolant and solvent. Ethylene glycol can also be used in the manufacture of pigments, pigment solvents, and dyes.
Metallurgical uses: Used as an extractant for metals such as chromium, aluminum, zinc, and copper.

Production method:
Ethylene glycol is typically produced through the hydration reaction of ethylene. Ethylene reacts with water under high pressure and high temperature to form ethylene glycol.

Safety information:
1. It is somewhat toxic and may cause harm to health, especially when inhaled, ingested, or in contact with the skin.
2. Long-term or excessive exposure to ethylene glycol may lead to diseases of the kidneys, liver, and nervous system.
3. When using ethylene glycol, protective gloves, goggles, and protective clothing should be worn to avoid direct contact with the skin and eyes. Operate in a well-ventilated environment and try to avoid inhaling its vapors.
