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
• Polymerization hazard: Polymerization reaction may become intense and may cause pressurization

4-Methoxybenzenelithium reacts violently with ethylene oxide at temperatures above -40C (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 317).

Ethylene oxide reacts with Grignard reagents to form alcohols (Dever, J. P., George, K. F., Hoffman, W. C. and Soo, H. 2004. Ethylene Oxide. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).

The polymerization of epoxides can be initiated by metal alkyls and metal aryls, as well as other anionic initiators (Quirk, R. P. and Monroy, V. M. 2004. Initiators, Anionic. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).

Hydrides of at least moderate reducing power will reduce epoxides (Eggeman, T. 2001. Hydrides. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).
