Ethylene Glycol
SINOBIO
29053100
Ethylene Glycol is an important organic chemical material with a wide range of industrial applications. The following is a detailed introduction about Ethylene Glycol:
Chemical formula and molecular weight: the chemical formula of ethylene glycol is C₂H₆O₂, and the molecular weight is 62.07.
Physical state: at room temperature and pressure, ethylene glycol is a colorless, transparent, viscous liquid with a sweet smell.
Physical Properties:
Melting point: -12.9℃
Boiling point: 197.3℃
Flash point: 111℃
Density: 1.13g/mL (25℃)
Solubility: Slightly soluble in ethyl ether, virtually insoluble in benzene and its homologues, chlorinated hydrocarbons, and petroleum ethers, but miscible with water, low-grade aliphatic alcohols, glycerol, acetic acid, acetone and other similar ketones, aldehydes, and pyridine.
1. Ethylene glycol is widely used in the fields of industry and people's livelihood. It is the core raw material for the manufacture of polyester products and can be used to synthesize polyester resins, polyester fibers and bottle-grade PET, etc.
2. The synthesized polyester fibers (polyester) are mostly used in clothing and home textiles, while bottle-grade PET is commonly found in various packaging containers, reflecting its core value in the field of polymer materials.
3. In fine chemicals, ethylene glycol can be used as a hygroscopic aid, plasticizer, surfactant, etc., and is also a key component in the production of synthetic fibers, etc.
4. It can be used as a solvent to help dyes and inks disperse, and can also be used as a gas dehydrating agent and wetting agent to enhance the surface affinity of materials.
5. Ethylene glycol, as an antifreeze, can protect automobile engines from running at low temperatures, and also acts as an efficient refrigerant in industrial cold transport.
6. It can be used as a condensing medium similar to water, participate in a variety of heat exchange processes, and play a significant role in the field of cold and heat control.

Ethylene glycol has a wide range of applications, mainly including:
1. Production of polyester fibers and plastics: Ethylene glycol is the main raw material for the production of polyethylene terephthalate (PET), which is the raw material for polyester fibers and polyester plastics.
2. Antifreeze and coolant: Ethylene glycol has a low freezing point and is often used as a medium for convection heat transfer in automotive cooling systems and liquid-cooled computers.
3. Solvents and lubricants: Ethylene glycol can be used as a solvent, lubricant, plasticizer, etc.
4. Medicines and pesticides: Ethylene glycol can be used to synthesize medicines, pesticides, etc.
5. Other applications: Ethylene glycol can also be used to produce surfactants, softeners, explosives, etc., and can be used as reagents, desiccants, etc.
