Ethylene Glycol Dibutyl Ether Usage And Synthesis

Description

Ethylene glycol dibutyl ether (EDBE) is a glycol ether with the chemical formula (C4H9OCH2)2. It is a clear liquid with an odor similar to that of acetone and diethyl ether. EDBE is soluble in water but insoluble in organic solvents such as benzene or toluene. EDBE has been shown to have hydroxyl and ether groups, which are essential for its chemical stability. The intramolecular hydrogen bond between the hydroxyl group and the ether oxygen atom is also an important factor in determining the structure of EDBE. EDBE is chemically stable at room temperature and can be found as a component of hydraulic fluids, paints, varnishes, lubricants, adhesives, cleaning agents, and degreasers.

Chemical Properties

Almost colorless liquid; slight odor. Slightly soluble in water. Combustible.

Uses

High-boiling inert solvent; specialized solvent and extraction applications.

General Description

Colorless liquid.

Air & Water Reactions

Oxidizes in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164].

Reactivity Profile

ETHYLENE GLYCOL DI-N-BUTYL ETHER may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides. Relatively inert in other reactions, which typically involve the breaking of the carbon-oxygen bond.

Health Hazard

Moderately toxic by ingestion and skin contact. Irritates skin and eyes.

Fire Hazard

Special Hazards of Combustion Products: On decomposition, ETHYLENE GLYCOL DI-N-BUTYL ETHER emits acrid smoke and irritating fumes.

Purification Methods

Shake the ether with aqueous 5% Na2CO3, dry with MgSO4 and store it with chromatographic alumina to prevent peroxide formation. [Beilstein 1 III 2083, 1 IV 2382.]
