Chemical Properties: Ethylene glycol has low volatility, high flash point, and greater hygroscopicity than glycerol. It is slightly soluble in ether and miscible with water in any proportion, significantly lowering the freezing point of water. It turns yellow or brown in the presence of iron impurities.
 

Applications

Ethylene glycol (MEG) is an important chemical raw material, primarily used in the production of polyester resin products, including polyester fibers, films, and PET bottles. Ethylene glycol solutions can be used as automotive antifreeze, with a 58% (by mass) solution having a freezing point of -48°C. Higher or lower concentrations result in a higher freezing point. It is also used as an auxiliary in the dye industry, and as a lubricant in tobacco and cosmetics.
