  • 1-chloro-2,3-epoxypropane appears as a clear colorless liquid with an irritating chloroform-like odor. Density 9.8 lb / gal. Flash point 87°F. Polymerizable. If polymerization takes place inside a closed container, the container is subject to violent rupture. Irritates the skin and respiratory system. Toxic by ingestion. A confirmed carcinogen. Vapors heavier than air. Used to make plastics and as a solvent.

  • Epichlorohydrin should be stored in tightly closed, labeled containers in fire-proof, cool, dry rooms. Apply ventilation across the floor. Epichlorohydrin attacks steel in the presence of moisture. The compound should be stored away from strong acids and bases, zinc, aluminium, metal chlorides, alcohol-containing material, isopropylamine, trichloroethylene, and oxidizing agents.

  • Vapour pressure, kPa at 20°C: 1.6

  • 3.29

  • Epichlorohydrin can be oxidized by free radical process in liquid or gas phases; these reactions may occur as photochemically initiated atmospheric reactions.
