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. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. [3] DEG is a widely used solvent. [4]
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 ...

Both ethanol and methanol have low flash points, 11–17 °C, making them highly flammable; diethylene glycol, with a flash point of 154 °C, is considered safer because spilled DEG fuel will not combust; it needs a wick to burn. The fuel is in a liquid form and thus the canister in which it is contained usually differs by having a more leak ...

Dioxane is produced by the acid-catalysed dehydration of diethylene glycol, which in turn is obtained from the hydrolysis of ethylene oxide. In 1985, the global production capacity for dioxane was between 11,000 and 14,000 tons. [4] In 1990, the total U.S. production volume of dioxane was between 5,250 and 9,150 tons. [5]
Nucleophilic polymerization of the epoxide groups gives a material that has the same backbone as polyethylene glycol, with allyl-ether side chains. The additional Lewis basic ether sites alter ion transport in the polymer and also affect the transient inter-chain crosslinking and glass transition temperature in the presence of metal ions.
Diethylene glycol diglycidyl ether (DEGDGE) is an organic chemical in the glycidyl ether family with the formula C 10 H 18 O 5.. The oxirane functionality makes it useful as a reactive diluent for epoxy resin viscosity reduction.
