Hazard Predictions

• Corrosive: Reaction products may be corrosive
• 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)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

Reactions of alkali metals and alcohols produce flammable H2 gas and corrosive metal alkoxides (Horn, M. and Horns, U. 2000. Alkoxides, Metal. Kirk-Othmer Encyclopedia of Chemical Technology. (Online); Falbe, J., Bahrmann, H., Lipps, W. and Mayer, D. 2000. Alcohols, Aliphatic. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Reactions of potassium with alcohols can be explosive in air (E.F. Pratt et al., J. Am. Chem. Soc., 1954, p. 54; Chiu, K.-W. 2005. Potassium. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).

Reactions of sodium and alcohols, including ethanol, produce flammable H2 gas (Eggeman, T. 2007. Sodium and Sodium Alloys. Kirk-Othmer Encyclopedia of Chemical Technology. (Online); A. Brandstrom, Acta Chem. Scand. 1951, 4, 1608-1610).
