Triethylene glycol is a member of a homologous series of polyethylene glycols.It is a colorless, odorless and stable liquid with high viscosity and a high boiling point. . Apart from its use as a raw material in the manufacture and synthesis of other products, TEG is known for its hygroscopic quality and its ability to dehumidify fl
The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water. Under these conditions, ethylene glycol yields of 90% can be achieved. The major byproducts are the oligomers diethylene glycol, triethylene glycol, and tetraethylene glycol. The separation of these oligomers and water is energy-intensive.
Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.

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 dimethylacrylate (EGDMA) is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol. [ 2 ] EGDMA can be used in free radical copolymer crosslinking reactions.
Their properties strongly depends on the substituent. A large family of acrylate-like polymers are derived from methyl methacrylate and many related esters, especially polymethyl methacrylate . A second large family of acrylate-like polymers are derived from ethyl cyanoacrylate , which gives rise to cyanoacrylates .
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.
