Diisopropyl ether, also called 2-isopropoxyisopropane or isopropyl ether, is a clear, colorless, fluid and highly flammable liquid with a typical ether odor. It has low water solubility but dissolves well in organic solvents and tends to form explosive peroxides. Compared with diethyl ether, it has a higher boiling point, lower vapor pressure and weaker water solubility, allowing efficient recovery after use as a solvent or extractant.
