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.
Chemical Formula: C₂H₆O₂
Structural Formula: HO-CH₂-CH₂-OH
Molecular Weight: 62.07 g/mol
CAS No.: 107-21-1
EINECS No.: 203-473-3
Synonyms: Glycol, 1,2-Ethylene Diol, Ethylene Diol
Appearance: Colorless, transparent, odorless, sweet-tasting viscous liquid.
Melting Point: -12.9℃
Boiling Point: 197.3℃
Density: 1.1155 g/cm³ (20℃)
Solubility: Miscible with water, ethanol, acetone, acetic acid, glycerol, pyridine, etc.
Slightly soluble in ether, almost insoluble in benzene, petroleum ether, and oils.
Hygroscopicity: Hygroscopic, requires airtight storage.
*Esterification: Reacts with organic or inorganic acids to form esters, which can be monoesters or diesters.
*Oxidation: Can be oxidized to glycolaldehyde, glyoxal, glycolic acid, oxalic acid, etc., under the action of a catalyst.
*Dehydration: Intramolecular or intermolecular dehydration occurs upon heating, forming cyclic acetals or dioxanes.
*Alkoxide Formation: Reacts with alkali metals or alkaline earth metals to form alkoxides.
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.
