摘要: Abstract Organic (hydro)peroxides, ROOR and ROOH, were generated either radiolytically in oxygenated aqueous solutions ( OH+RH→R +H2O; R +O2→ROO ; 2 ROO →ROOR+O2; +HO2 /O2 −+H+→ROOH+O2) or by ozonolysis (R2C=CR2+O3+H2O→R2C=O+R2C(OH)OOH). Their pseudo-first-order kinetics with molybdate-activated iodide allows us to characterise a given peroxide, since the half-lives vary more than seven orders of magnitude. Some (hydro)peroxides do not react under these conditions, e.g. dimethylperoxide, but very reactive ones, formic peracid, even require molybdate catalysis. For including H2O2, HPLC post-column reaction is convenient method for spotting (hydro)peroxide chromatogram its quantitative determination. Recommendations are how use this assay determination mixtures different reactivity.
