Materials liable to form peroxides in storage

The following materials may form peroxides in storage, when in contact with air. A peroxide-containing material always constitutes an explosion risk, but the risk is particularly serious if the material is heated. This is because peroxides are generally less volatile than the compound from which they are formed, (usually having lower vapor pressure because of increased intermolecular forces between the - now strongly polar - peroxide molecules). Distillation therefore leads to progressive concentration of the peroxide. The combination of a concentrated solution of peroxide with heating can result in explosive decomposition.

•·         Aldehydes

•·         Ethers, especially cyclic ethers and those containing primary and secondary alcohol groups

•·         Compounds containing benzylic hydrogen atoms (particularly if the hydrogens are on tertiary carbon atoms)

•·         Compounds containing the allylic structure, including most alkenes

•·         Vinyl and vinylidene compounds

Among the more widely-used compounds which may form peroxides in storage are:

•·         Acetal

•·         Cumene

•·         Cyclohexene

•·         Cyclooctene

•·         Decahydronaphthalene

•·         Decalin

•·         Diacetylene

•·         Dicyclopentadiene

•·         Diethyl ether

•·         Diethylene glycol

•·         Diisopropyl ether - see isopropyl ether

•·         Dimethyl ether

•·         Dioxane

•·         Divinyl acetylene

•·         Ethylene glycol dimethyl ether (glyme)

•·         Isopropyl ether

•·         Methyl acetylene

•·         Sodium amide

•·         Tetrahydrofuran (THF)
