Hazard Predictions

• 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
• Toxic: Reaction products may be toxic

Diethyl ether explodes or ignites on contact with BrF3 (Sharpe, A.G. et al. 1948. Journal of the Chemical Society 2136), BrF5 (Mellor, J.W. 1956. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Longmans, Green and Co Ltd. Volume 2, Supplemental 1. pp. 172), or ClF3 (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 1614).

Tetrahydrofuran (reaction may be light-promoted) (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 114) and diethyl ether react violently with bromine (Urben 110); if the bromine is impure, diethyl ether may ignite (University Safety Association. 1989. Safety Digest 34:14).

Diethyl ether ignites on contact with IF7 (Booth, H.S. et al. 1947. Chemical Reviews 41:428), or with chlorine if light is present (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 1298).

Chloromethyl ethyl ether liberates toxic HCl gas upon exposure to benzene (Walker, F. J., Formaldehyde. New York: ACS Monograph Series, 1964, pp. 279) It is likely that other halogenated ethers would produce analogous HX gases (Predicted by comparison to similar reactions, citation needed).
