112-60-7 Usage

Chemical Properties

Tetraethylene glycol is a high-boiling, clear liquid of low volatility. hygroscopic. It is completely miscible with water and a wide variety of organic solvents. insoluble in benzene, toluene, or gasoline. Combustible. For certain aliphatic hydrocarbons, it has a very slight affinity. Tetraethylene glycol is used as a coupling agent for blending water-soluble and water-insoluble compounds in such formulations as lubricants, glues, cork and textile products, etc.

Reactivity Profile

Bis[2-(2-hydroxyethoxy)ethyl] ether 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. May attack some forms of plastics [USCG, 1999].

Air & Water Reactions

Water soluble.

Safety Profile

Mildly toxic by ingestion. A sktn and eye irritant. Combustible when exposed to heat or flame; can react with oxidzing materials. To fight fire, use alcohol foam, water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

General Description

Colorless to straw-colored liquid with a mild odor. Sinks and mixes with water.

Uses

Solvent for nitrocellulose, plasticizer, lacquers, coating compositions.

Production Methods

Tetraethylene glycol is prepared commercially by adding ethylene oxide to ethylene glycol, diethylene glycol, or water in the presence of a suitable catalyst.

Health Hazard

Compound is nonirritating. No symptoms observed by any exposure route.
