Hazard Predictions

• 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

Inorganic cyanides react with acids as weak as carbonic acid to release HCN gas (Gail, E. et al. 2004. Cyano Compounds, Inorganic. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA (Online); Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 974). Phenol is a very weak acid, so an acid-base reaction between inorganic cyanides and phenol derivatives is unlikely to be rapid, but gas build-up may slowly occur in closed systems. Also, it should be noted that phenol derivatives with electron-withdrawing substituents (e.g. halides, nitro, acyl) on the aromatic ring are much more acidic than phenol itself, so there is a higher chance of an acid-base reaction with those compounds. 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.
