Diethylene Glycol (DEG) is an organic compound, It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. Diethylene glycol is similar in properties to MEG (Mono Ethylene Glycol), but DEG has a higher boiling point, viscosity, and specific gravity.
DEG is produced by the partial hydrolysis of ethylene oxide. Depending on the conditions, varying amounts of DEG and related glycols are produced. The resulting product is two ethylene glycol molecules joined by an ether bond,
DEG is a widely used solvent. Diethylene glycol (DEG) is a valuable chemical intermediate used in the production of unsaturated polyester resins (UPR), plasticizers, acrylate and methacrylate resins and urethanes. DEG is used as a component of multiple different products including antifreeze preparations, cosmetics, lubricants, brake fluids, wallpaper strippers, heating/cooling fuel and as a plasticizer.
