Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Toxic: Reaction products may be toxic

Phosgene can react with ketones, releasing toxic HCl gas as a byproduct (Dunlap, K.L. 2005. Phosgene. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

The preparation of isopropenyl chloroformate by the reaction of acetone with phosgene has been reported (M. P. Matuszak. J. Amer. Chem. Soc., 56, p. 2007 (1934)).

Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility. The generation of gases may be rather slow, however confinement may lead to dangerous conditions.

Potential Gas Byproducts

• Hydrogen Chloride (HCl)
• Hydrogen Halide (HX)
• Acid Fumes
