WebJul 5, 2024 · Peroxide Formation Many ethers can react with oxygen to form explosive peroxide compounds n a free radical process called autoxidation. For this reason ethers should not be stored for long periods of time and should not be stored in glass bottles. The danger is particularly acute when ether solutions are distilled to near dryness. 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 the associated risk of explosion.
