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

Tertiary hydroperoxides are decomposed by bases, forming combustion-promoting O2 gas (Klenk, H., P.H. Gotz, R. Siegmeier, and W. Mayr. 2002. Peroxy Compounds, Organic. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)); such reactions are exothermic and self-accelerating (Sanchez, J. and Myers, T. N. 2000. Peroxides and Peroxide Compounds, Organic Peroxides. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)), and may proceed violently (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 392).

NaOH or KOH will react with peroxides in non-fresh ether solutions, potentially causing an explosion (Recommended Handling Procedures. 1964. THF Brochure FC3-664, Wilmington, Du Pont).

KOH and potassium peroxodisulfate ignite on contact (British Chemical Industrial Safety Council. 1965. Quarterly Safety Summary 36, 41).

Dimethylol peroxide reacts with sodium hydroxide to liberate flammable H2 gas (Walker, F. J., Formaldehyde. New York: ACS Monograph Series, 1964, pp. 245).

Potential Gas Byproducts
