The waste TEG produced by this process has been found to contain enough benzene to be classified as hazardous waste [3] (benzene concentration greater than 0.5 mg/L). Triethylene glycol is well established as a relatively mild disinfectant toward a variety of bacteria, influenza A viruses and spores of Penicillium notatum fungi. [4]
Diethylene glycol is one of several glycols derived from ethylene oxide. Glycols related to and co-produced with diethylene glycol and having the formula HOCH 2 CH 2 (OCH 2 CH 2) n OH are: n = 0 ethylene glycol ("antifreeze"); monoethylene glycol MEG; n = 1 DEG; n = 2 triethylene glycol, TEG, or triglycol; n = 3 tetraethylene glycol; n = 4 ...
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.

Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, respectively.Typically, E-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while P-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives.
Dibutylmagnesium can be obtained by reaction of butyllithium with magnesium butylchloride and subsequent addition of magnesium 2-ethylhexanoate. [3] The compound can also be prepared by hydrogenation of magnesium, followed by reaction with 1-butene . [ 1 ]
Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economical means of water removal from these streams. [1] Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol ...
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation. It is soluble in polar solvents.
