Di-tert-butyl ether (also known as methylisopropyl ether), sometimes written as t-Bu2O, is tertiary ether, sometimes used as a solvent, albeit expensive.
Di-tert-butyl ether will burn when ignited in air.
t-Bu2O is a colorless liquid, with a penetrating camphor-like odor. I has a density of 0.7642 g/cm3 at 20 °C.
Di-tert-butyl ether is sold by various chemical suppliers and can be purchased online.
Di-tert-butyl ether can be prepared by reacting a tert-butyl halide, such as tert-butyl chloride, with very dry silver carbonate, by continuous stirring in diethyl ether at room temperature, for 24 hours. Pentane can also be used as a solvent. Byproducts of this reaction include tert-butanol, isobutylene, carbon dioxide, and silver chloride.
The Williamson route does not work for this compound, and will yield isobutylene and tert-butanol instead.
Di-tert-butyl ether is flammable and irritant. Handle with care.
In closed bottles, away from light and strong acids. Since it resists auto-oxidation, t-Bu2O does not form peroxides upon storage.
Di-tert-butyl ether can be destroyed by burning it outside.
