Hazard Predictions

• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

Dioxane reacts explosively with Raney Ni at 210C (Mozingo, R. 1955. Organic Synthetics 3:182).

Aluminum powder can abstract the oxygen atom from diethyl ether, even at very low temperatures. Reactive hydrocarbon radicals may be produced during this process (Murdock, T. O., Ph.D. Thesis, Univ. N. Dakota, 1977).

Diethyl ether is used to dissolve magnesium metal for preparation of Grignard reagents. The lone pairs in ether stabilize the metal, and do not react with the atom (Loudon, Marc. 2002. Organic Chemistry. 4th ed. New York: Oxford University Press. p. 334-336).
