Diethyl ether hydroperoxide is the organic compound with the formula C2H5OCH(OOH)CH3. It is a colorless, distillable liquid. Diethyl ether hydroperoxide and its condensation products are blamed for the explosive organic peroxides that slowly form upon exposure of diethyl ether to ambient air and … See more Diethyl ether hydroperoxide can be formed by the photooxygenation of diethyl ether. This is a radical process, driven by UV excitation of molecular oxygen into a more reactive form. Its formation is usually undesirable due to … See more Diethyl ether peroxides can be detected with a potassium iodide (KI) solution in acetic acid or potassium iodide / starch paper. A positive test results in the formation of See more WebThis material is >95% di-ethyl ether, which can form peroxides over time. Users of such materials in ether or THF should realize that peroxides could form. Other changes are also being made because of this incident.
