Hazard Predictions

• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

Acetaldehyde reacts violently with amines (MCA Safety Datasheet 43, Manufacturing Chemists' Association, Washington, 1952).

Tertiary amines promote exothermic aldol condensations between aldehydes and/or ketones (Kohlpaintner, C., M. Schulte, J. Falbe, P. Lappe, and J. Weber. 2002. Aldehydes, Aliphatic and Araliphatic. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)).

Hazards involving Acrolein (unsaturated aldehyde):

Acrolein polymerizes explosively on contact with amines (Arntz, D., M. Hopp, S. Jacobi, J. Sauer, T. Ohara, T. Sato, N. Shimizu, G. Prescher, H. Schwind, and O. Weiberg. 2002. Acrolein. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)).

Ethylenediamine may react violently with acrolein (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 1554.).

Amines such as dimethylamine and triethylamine promote polymerization of acrolein (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 417.).
