Bis(2-butoxyethyl)ether Usage And Synthesis
Chemical Properties clear colorless to yellowish liquid
Uses Butyl diglyme is used to extract gold from hydrochloric acid solutions containing other metals. Treatment of the diglyme extract with hydrogen or oxalic acid precipitates the ionic gold as gold powder.
General Description Colorless liquid. Floats on water.
Air & Water Reactions Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Insoluble in water.
Reactivity Profile Bis(2-butoxyethyl)ether may react violently with strong oxidizing agents. Incompatible with nitric acid. May form salts with strong acids and addition complexes with Lewis acids. In other reactions, which typically involve the breaking of the carbon-oxygen bond, relatively inert.
Health Hazard May be harmful by inhalation, ingestion and skin absorption. Causes eye and skin irritation. Material is irritating to mucous membrane and upper respiratory tract.
Fire Hazard Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back.
