![]() ![]() ![]() A dilute solution of diethylene glycol can also be used as a cryoprotectant however, ethylene glycol is much more commonly used. skin cream and lotions, deodorants), DEG is often replaced by selected diethylene glycol ethers. It is also a component in brake fluid, lubricants, wallpaper strippers, artificial fog and haze solutions, and heating/cooking fuel. It is a humectant for tobacco, cork, printing ink, and glue. It is a solvent for nitrocellulose, resins, dyes, oils, and other organic compounds. DEG is used as a building block in organic synthesis, e.g. These compounds are all hydrophilic, more so than most diols, by virtue of the ether functionality.ĭiethylene glycol is used in the manufacture of saturated and unsaturated polyester resins, polyurethanes, and plasticizers. n = 2 triethylene glycol, TEG, or triglycol.n = 0 ethylene glycol ("antifreeze") monoethylene glycol MEG.Glycols related to and coproduced with diethylene glycol and have the formula HOCH 2CH 2(OCH 2CH 2) nOH are: Availability of DEG will depend on demand for derivatives of the primary product, ethylene glycol, rather than on DEG market requirements." Structure of DEG and related polyols ĭiethylene glycol is one of several glycols derived from ethylene oxide. Ethylene glycol is by far the largest volume of the glycol products in a variety of applications. The industry generally operates to maximize MEG production. "Diethylene glycol is derived as a co-product with ethylene glycol (MEG) and triethylene glycol. The resulting product is two ethylene glycol molecules joined by an ether bond. Depending on the conditions, varying amounts of DEG and related glycols are produced. Preparation ĭEG is produced by the partial hydrolysis of ethylene oxide. It can be a contaminant in consumer products this has resulted in numerous epidemics of poisoning since the early 20th century. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. It is a four carbon dimer of ethylene glycol. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. Diethylene glycol ( DEG) is an organic compound with the formula (HOCH 2CH 2) 2O. ![]()
