Ethylene glycol, also known as glycol or 1,2-ethanediol, abbreviated as EG, has the chemical formula (CH2OH)2 and is the simplest diol. It is a liquid under normal temperature and pressure conditions and is odorless. Ethylene glycol is miscible with water and acetone, but has limited solubility in ethers. It is used as a solvent, antifreeze agent, and raw material for the synthesis of polyester.
