Ethylene Glycol

Ethylene glycol, also known as "glycol" or "1,2-ethanediol," is abbreviated as EG. Its chemical formula is (CH2OH)2 and it is a simple diol. Ethylene glycol is a colorless, odorless, sweet-tasting liquid with toxicity to animals. It is miscible with water and acetone but has low solubility in ethers. It is used as a solvent, antifreeze, and as a raw material for the synthesis of polyester. The polymer of ethylene glycol, polyethylene glycol (PEG), is a phase transfer catalyst and is also used in cell fusion.

3 Chemical Properties

Due to its low molecular weight and活泼 nature, it can undergo esterification, etherification, alkylation, oxidation, acetal formation, dehydration, and other reactions.
