Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Toxic: Reaction products may be toxic

Isocyanates may react with iron carbonyl to liberate toxic and flammable CO gas (Smith, P. A. S., Open-Chain Nitrogen Compounds, Vol. I. New York: W. A. Benjamin, Inc., 1965, pp. 225).

The reaction of isocyanates with alcohols to form carbamates is catalyzed by a variety of organometallic compounds. This reaction is the bedrock of the polyurethane industry (Richter, R. H. and Priester, R. D. 2000. Isocyanates, Organic. Kirk-Othmer Encyclopedia of Chemical Technology.
