![]() For safety reasons, methyl tert-butyl ether is often used as an alternative solvent. Peroxides may be removed by shaking the ether with an aqueous solution of iron(II) sulfate or sodium metabisulfite. It is recommended once every 3 months for diisopropyl ether compared to once every 12 months for ethyl ether. The stored solvent are generally be tested for the presence of peroxides. Antioxidants can be used to prevent this process. Some laboratory procedures recommend use of freshly opened bottles. Many explosions have been known to occur during handling or processing of old diisopropyl ether. This reaction proceeds more easily than for ethyl ether due to the increased lability of the C-H bond adjacent to oxygen. Safety ĭiisopropyl ether forms explosive peroxides upon standing in air. Diisopropyl ether is used for converting bromoboranes, which are thermally labile, into isopropoxy derivatives. In the laboratory, diisopropyl ether is useful for recrystallizations because it has a wide liquid range. ![]() It has also been used as an antiknock agent. Diisopropyl ether is used as a specialized solvent to remove or extract polar organic compounds from aqueous solutions, e.g. Whereas at 20 ☌, diethyl ether will dissolve 1% by weight water, diisopropyl ether only dissolves 0.88%.
