Editing Diisopropyl ether (section)

==Safety==
Diisopropyl ether forms explosive [[organic peroxide|peroxides]] upon standing in air. This reaction proceeds more easily than for [[ethyl ether]] due to the increased lability of the  C-H bond adjacent to oxygen. Many explosions have been known to occur during handling or processing of old diisopropyl ether.<ref>{{cite book | last=Matyáš | first=Robert | last2=Pachman | first2=Jiří. | title=Primary explosives | publisher=Springer | publication-place=Berlin | date=2013 | isbn=978-3-642-28436-6 | oclc=832350093 |page=272}}</ref> Some laboratory procedures recommend use of freshly opened bottles.<ref name=OS/> Antioxidants can be used to prevent this process. The stored solvent is generally tested for the presence of peroxides.  It is recommended once every 3 months for diisopropyl ether compared to once every 12 months for ethyl ether.<ref name="OSH Answers: Organic peroxides">{{Cite web | url=https://www.ccohs.ca | title=Organic Peroxides - Hazards : OSH Answers | publisher = Canadian Centre for Occupational Health and Safety, Government of Canada | website=www.ccohs.ca }}</ref> Peroxides may be removed by shaking the ether with an aqueous solution of [[iron(II) sulfate]] or [[sodium metabisulfite]].<ref>{{cite book |author1=Chai, Christina Li Lin |author2=Armarego, W.
