Hazard Predictions

• 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)

At significantly elevated temperatures, KOH and NaOH react exothermically with glycols, evolving flammable H2 gas (Cardillo, P. et al. 1982. Chim. e Ind. (Milan) 64:781-784).

Methanol, ethanol, n-propanol, and 2-propanol ignite on contact with potassium tert-butoxide (Manwaring, R. et al. 1973. Chemistry and Industry 172).

Ethanol may ignite on contact with cesium oxide (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. Vol. 1, pp. 1390).

Heat of mixing tests show approximately -30cal/g evolved for a 50/50 mixture of 50% NaOH in water and various alcohols and glycols (personal communication).
