WebFree radicals from benzoyl peroxide are used to initiate methyl methacrylate polymerization, but oxygen can provide such radicals, especially if certain transition metal impurities are present. Ultra-violet light may also open the double bond and so provide a double free radical (see 24§6.2). WebThe reaction proceeds through free radical mechanism as peroxide form hydroxide radicals which react with hydrogen bromide to form bromine radical. The bromine radical react with 1-methyl...

WebThe DFT calculations indicated that methanol formation via methyl peroxide (CH 3 OOH*) on [Fe 2 (μ-OH) 2 O 2] is the most favorable pathway compared to the direct formation of methanol via CH 3 O*. The formed CH 3 OH is easily further oxidized by hydroxyl radicals (˙OH) resulting in non-selective methane oxidation.
