Monoethylene Glycol (MEG), chemically identified as 1,2-ethanediol, is a fundamental organic compound and the simplest member of the glycol family. It is a clear, colorless, virtually odorless, and slightly viscous liquid characterized by its hygroscopic nature and complete miscibility with water, Alcohol, and many organic solvents. Produced industrially primarily through the liquid-phase hydration of ethylene oxide, MEG is a cornerstone of the global petrochemical industry. Its molecular structure—consisting of two hydroxyl groups on adjacent carbon atoms—provides high reactivity, making it an essential chemical intermediate. MEG is most prominently utilized in the manufacture of polyester fibers and polyethylene terephthalate (PET) resins, which are ubiquitous in the packaging and textile sectors. Furthermore, its ability to significantly lower the freezing point of water makes it the industry standard for automotive coolants and de-icing fluids. While highly versatile, MEG is toxic if ingested and requires stringent safety protocols during handling and disposal.
