Web8.7 Peroxide Forming Compounds. Many commonly used chemicals; organic solvents in particular, can form shock, heat, or friction sensitive peroxides upon exposure to oxygen. Once peroxides have formed, an explosion can result during routine handling, such as twisting the cap off a bottle – if peroxides are formed in the threads of the cap. WebGeneral categories of peroxide forming chemicals include Aldehydes, Ketones, Ethers, Alkenes and Alkali metals. Some of these chemicals come with inhibitors added (e.g. BHT) to help prevent peroxide formation, but formation can still occur over time. Commonly used peroxide formers include diethyl ether, tetrahydrofuran (THF), and cyclohexene.
