Hazard Predictions

• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
• Polymerization hazard: Polymerization reaction may become intense and may cause pressurization

Ethylene oxide and 3-nitroaniline reacted in an autoclave at 130 C and exploded (Bretherick, L. 1996. Bretherick's Handbook of Reactive Chemical Hazards. Fifth Ed. Urben, P.G., Ed. Butterworth-Heinemann, Boston, MA. Vol. 1, p 317).

Ethylene oxide can explosively polymerize on contact with amines, causing pressurization (Gupta, A.K. 1949. J. Soc. Chem. (Ind.) 68: 179; British Chemical Industrial Safety Council. 1966. Quarterly Safety Summaries, London, British Chemical Industries Safety Council, 1966, vol. 37, p. 44).

Aniline reacts explosively with 1-chloro-2,3-epoxypropane (Hearfield, F. 1980. Chemical Abstracts 92:115649; Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 254).

Flammable hydrocarbons were released during decomposition in the latter stages of a runaway polymerization reaction between amines and epoxides (Thermal Decomposition of Polymers by Craig Beyler and Marcelo Hirschler, Section 1, Chapter 7, p 1-128).
