Ethylene glycol, affectionately known in the chemical community as glycol or 1, 2-ethylenediol, is succinctly abbreviated as EG. With its chemical composition marked by (CH20H)2, this simplest of diols presents itself as a colorless and odorless liquid, characterized by its sweet taste and notably low toxicity to animals. A versatile solvent, it harmonizes effortlessly with water and acetone, though it shows a lower affinity for ethers. EG's significance shines brightly in its role as a solvent, antifreeze, and a vital raw material for polyester synthesis. Predominantly, it fuels the creation of polyester, polyester resin, desiccants, plasticizers, surfactants, and synthetic fibers. Its utility extends beyond this, serving as a solvent for dyes and inks, and crafting antifreeze agents for engines. The production of synthetic resin PET, fiber-grade PET (polyester fibers, bottles), and sheet-grade PET (for mineral water bottles) can be attributed to this compound. The reach of EG spans the production of alkyd resins, glyoxal, and its pivotal role as an antifreeze. Beyond automotive antifreeze, it serves industrious roles in industrial cooling systems as a heat transfer medium, and its ability as a condensing agent akin to water is unparalleled.
