Hazard Information

General Description
Clear, colorless liquid with an agreeable aromatic odor.
Reactivity Profile
1,3-PROPYLENE OXIDE(503-30-0) reacts with Grignard reagents and organolithium compounds. 1,3-PROPYLENE OXIDE(503-30-0) is also incompatible with oxidizing agents and strong acids. . An explosion occurred when propylene oxide was added to epoxy resin. Polymerization was catalyzed by amine accelerator in the resin [Bretherick 1995]. Propylene oxide and sodium hydroxide base-catalyzed the polymerization of the former, causing ignition and explosion of a drum of the crude product. [Combust Sci. Technol., 1983].
Air & Water Reactions
Highly flammable. Water soluble.
Fire Hazard
This chemical is flammable.
