Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Toxic: Reaction products may be toxic

Acrolein may act as either a diene or dieneophile in Diels-Alder reactions; reactions with a diene are typically exothermic and rapid even at room temperature (Etzkorn, W.G., S.E. Pedersen, and T.E. Snead. 2004. Acrolein and derivatives. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

The Diels-Alder reaction between acrolein and trienes is also exothermic, and could result in the release of toxic and flammable carbon monoxide and flammable hydrogen gases (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 417.); the reaction between crotonaldehyde and 1,3-butadiene is violent (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 964.).
