Stability:
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

Hazard Information

General Description
A clear colorless liquid with an ethereal odor. Flash point-18°F. Less dense than water. Vapors heavier than air.
Reactivity Profile
Ethers, such as DIISOPROPYL ETHER, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert. Mixing diisopropyl ether in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, [NFPA 1991].
Air & Water Reactions
Highly flammable. Slightly soluble in water. Form explosive peroxide in storage. A flask of DIISOPROPYL ETHER(108-20-3) was heated on a steam bath with gentle shaking when an explosion occurred. In a second instance, an explosion occurred after practically all the ether had been distilled, [MCA Guide for Safety(1972)].
Hazard
Flammable, dangerous fire risk, explosive limits in air 1.4–21%. Toxic by inhalation, strong irritant.
Health Hazard
Inhalation causes anesthesia, nausea, headache, dizziness, and irritation of the eyes and nose. Contact of liquid with eyes causes only minor injury; repeated contact with skin will remove natural oils and may cause dermatitis.
Fire Hazard
Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. Containers may explode when heated.
