Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
The handling of this chemical may incur notable safety precautions. ... Temperature dependence of ethylene glycol vapor pressure. Uses formula ...
Polymerization of ethylene oxide is an exothermic process. Overheating or contaminating ethylene oxide with catalysts, such as alkalis or metal oxides, can lead to runaway polymerization, which can end in an explosion after a few hours. Polyethylene oxide, or high-molecular-weight polyethylene glycol, is synthesized by suspension polymerization.
Diethylene glycol (DEG) is an organic compound with the formula (HOCH 2 CH 2) 2 O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol.
Triethylene glycol, TEG, or triglycol is a colorless odorless viscous liquid with molecular formula HOCH 2 CH 2 OCH 2 CH 2 OCH 2 CH 2 OH. It is used as a plasticizer for vinyl polymers. It is also used in air sanitizer products, such as "Oust" [1] or "Clean and Pure". When aerosolized it acts as a disinfectant.
Ethylene is oxidized to produce ethylene oxide, a key raw material in the production of surfactants and detergents by ethoxylation. Ethylene oxide is also hydrolyzed to produce ethylene glycol, widely used as an automotive antifreeze as well as higher molecular weight glycols, glycol ethers, and polyethylene terephthalate.

The molecular formula C 2 H 6 O 2 (molar mass: 62.07 g/mol, exact mass: 62.03678 u) may refer to: Ethylene glycol (ethane-1,2-diol) Ethyl hydroperoxide;
Here, ethylene oxide is obtained as the overhead product, whereas the bottom product obtained is known as the glycol bleed. When ethylene oxide is scrubbed from the recycle gas with an aqueous solution, ethylene glycols (viz. mono-ethylene glycol, di-ethylene glycol and other poly-ethylene glycols) get unavoidably produced.
