Stability: Extremely flammable. This material is a serious fire and explosion risk. Vapour may travel considerable distances to an ignition source, which need not be an open flame, but may be a hot plate, steam pipe, etc. Vapour may be ignited by the static electricty which can build up when isopropyl ether is being poured from one vessel
LogP 2.4 at 20℃

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.
