Triethylene glycol Chemical Properties,Uses,Production

Chemical Properties

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.


triethylene glycol is a solvent prepared from ethylene oxide and ethylene glycol.


In various plastics to increase pliability; in air disinfection.


ChEBI: A poly(ethylene glycol) that is octane-1,8-diol in which the carbon atoms at positions 3 and 6 have been replaced by oxygen atoms.

General Description

Colorless liquid with a mild odor. Dense than water.

Reactivity Profile

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].

Health Hazard

Vapor and liquid are unlikely to cause harm.

Fire Hazard

Flash Point (°F): 350 ℃, 330 ℃; Flammable Limits in Air (%): 0.9-9.2; Fire Extinguishing Agents: Alcohol foam, dry chemical, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water or foam may cause frothing; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 700; Electrical Hazard: Not pertinent; Burning Rate: 1.7 mm/min.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

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.

Purification Methods

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.]
