Ethylene glycol, often called glycol or 1, 2-ethylenediol and abbreviated as EG, boasts the chemical formula (CH2OH)2. Renowned as the simplest diol, this remarkable compound is a colorless, odorless liquid with a sweet taste and low animal toxicity. It effortlessly blends with water and acetone, yet maintains a limited solubility in ethers. Ethylene glycol shines as a versatile ingredient in various applications: serving as a solvent, antifreeze, and a pivotal raw material in polyester synthesis. Primarily utilized in crafting polyester, polyester resin, desiccant, plasticizer, surfactant, and synthetic fibers, its capabilities extend to functioning as a solvent for dyes and inks. It is instrumental in formulating antifreeze for engines and gas dehydrating agents, as well as in resin manufacturing. Beyond these, it acts as a wetting agent for cellophane, fibers, leather, and adhesives. Its synthetic prowess allows the creation of PET, both fiber-grade (polyester fiber) and bottle-grade for mineral water containers. Moreover, it contributes to the production of alkyd resins, glyoxal, and serves in industrial cooling systems as a heat transfer medium, often likened to water in its condensing capabilities.
