Description and Uses
Diisopropyl ether [108-20-3], also known as 2-isopropoxyisopropane or isopropyl ether, is a clear, colorless, mobile, highly flammable liquid with a characteristic ethereal odor. Its solubility in water is low, but it is soluble in organic solvents and readily forms explosive peroxides. It has a higher boiling point, a lower vapor pressure, and a lower water solubility than diethyl ether, which means that diisopropyl ether can be recovered without significant loss after use as a solvent or as an extractant.
Isopropyl ether is used as a solvent for oils,waxes, resins, and dyes; and as a varnishremover.
