1. Haagen-Smit identified the substance they collected as a peroxy organic material. 2. Other bleaching agents include 6-phthalimido peroxy hexanoic acid and sodium perborate. 3. Oxidation by peroxy acids is efficient for higher alkenes, but not for ethylene. 4. Rodent Alox15 enzymes, in contrast, produce almost exclusively ?-9 peroxy intermediates. 5. Bock also discovered that peroxy compounds are effective initiators in the emulsion polymerization of conjugated diolefines. 6. The radical intermediate formed by this reacts rapidly with oxygen to give a peroxy radical HO 2" 7. In the presence of oxygen, the alkyl radical is trapped and forms an organic peroxy radical. 8. Peroxy acids, such as peracetic acid and meta-chloroperoxybenzoic acid are also typically produced using hydrogen peroxide.9. It is the ease of splitting the peroxy group to give two free radicals that makes organic peroxides so useful. 10. With increasing temperature, the intensity may decrease because of the disappearance of peroxy radicals required for the above glow reactions.
