Ethylene glycol, often referred to as glycol or 1, 2-ethylenediol, is succinctly abbreviated as EG. Boasting the chemical formula (CH20H)2, this compound is recognized as the simplest diol. Ethylene glycol presents itself as a colorless, odorless liquid with a sweet taste and minimal toxicity to animals, ensuring environmental compatibility. Its versatility is evident as it seamlessly blends with water and acetone, while demonstrating limited solubility in ethers. This dynamic compound serves multiple roles: as a solvent, an antifreeze, and a crucial raw material in the synthesis of polyester. Predominantly, it is instrumental in the production of polyester, polyester resin, desiccants, plasticizers, surfactants, and synthetic fibers. Furthermore, ethylene glycol acts as a solvent for dyes and inks, formulates engine antifreeze, and is integral in gas dehydration and resin manufacturing. Its application extends to serving as a wetting agent for materials such as cellophane, fibers, leather, and adhesives. Beyond these uses, it facilitates the production of synthetic resin PET, encompassing fiber-grade PET (polyester fiber), bottles, and sheet-grade PET quintessential for crafting mineral water bottles. Additionally, it plays a role in producing alkyd resins, glyoxal, and functions as an industrial antifreeze, predominantly utilized in cooling systems as an efficient heat transfer medium. Ethylene glycol is also employed as a condensing agent, akin to water, showcasing its multifaceted utility.
