msds information

propionaldehyde usage and synthesis

chemical properties	colourless liquid
general description	a clear colorless liquid with an overpowering fruity-like odor. less dense than water. flash point 15°f. vapors are heavier than air.
air & water reactions	highly flammable. soluble in water.
reactivity profile	propionaldehyde may form explosive peroxides. reacts vigorously with oxidizing agents. explosive in the form of vapor when exposed to heat or flame [lewis]. incompatible with strong bases and strong reducing agents. vigorous polymerization reaction with methyl methacrylate. polymerization may also occur in the presence of acids or caustics .
health hazard	vapors will irritate nose and throat, and may cause nausea and vomiting. liquid causes eye irritation.
fire hazard	behavior in fire: vapor is heavier than air and may travel considerable distance to a source of ignition and flash back.
