2,2'-(Ethylenedioxy)diethanol is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. Reacts with strong oxidants. [Handling Chemicals Safely 1980. p. 932].
ChEBI: A poly(ethylene glycol) that is octane-1,8-diol in which the carbon atoms at positions 3 and 6 have been replaced by oxygen atoms.
Dry the glycol with CaSO4 for 1 week, then it is repeatedly and very slowly fractionally distilled under a vacuum. Store it in a vacuum desiccator over P2O5. It is very hygroscopic. [Beilstein 1 IV 2400.]
triethylene glycol is a solvent prepared from ethylene oxide and ethylene glycol.
In various plastics to increase pliability; in air disinfection.
Vapor and liquid are unlikely to cause harm.
Triethylene glycol is a clear, colorless, viscous, stable liquid with a slightly sweetish odor. Soluble in water; immiscible with benzene, toluene, and gasoline. Combustible. Because it has two ether and two hydroxyl groups its chemical properties are closety related to ethers and primary alcohols. It is a good solvent for gums, resins, nitrocellulose, steam-set printing inks and wood stains. With a low vapor pressure and a high boiling point, its uses and properties are similar to those of ethylene glycol and diethylene glycol. Because it is an efficient hygroscopic agent it serves as a liquid desiccant for removing water from natural gas. It is also used in air conditioning systems designed to dehumidify air.
Poison by intravenous
route. Mildly toxic to humans by ingestion.
Experimental reproductive effects. An eye
and skin irritant. Many glycol ether
compounds have dangerous human
reproductive effects. Combustible when
exposed to heat or flame. Can react with
oxidizing materials. Explosive in the form of
vapor when exposed to heat, flame, or
spark. To fight fire, use alcohol foam, dry
chemical. When heated to decomposition it
emits acrid smoke and irritating fumes. See
also ESTERS and GLYCOL ETHERS.
Triethylene glycol, like diethylene glycol, is produced commercially
as a by-product of ethylene glycol production.
Its formation is favored by a high ethylene oxide to water
