Ethylene Glycol

CAS NO.:107-21-1

MF:C2H6O2

MW:62.07

Nature:A colorless, odorless, sweet-tasting viscous liquid that is miscible with water and acetone.

Application:Ethylene glycol is primarily used in the formulation of antifreeze for automotive cooling systems and in the production of polyethylene terephthalate (a raw material for polyester fibers and plastics). It can also be used to produce its synthetic resins, solvents, lubricants, surfactants, softeners, humectants, and explosives. Ethylene glycol is often used as a substitute for glycerin in the leather and pharmaceutical industries, serving as a hydrating agent and solvent, respectively. While ethylene glycol has strong dissolving power, it is easily metabolized and oxidized to produce toxic oxalic acid, thus limiting its widespread use as a solvent. Adding ethylene glycol to hydraulic fluids can prevent the corrosion of rubber in the system by oil-based hydraulic fluids. Water-based hydraulic fluids with ethylene glycol as the main component are non-flammable and used in aircraft, automobiles, and molding machines operating in high-temperature environments.
