For materials containing more than 1.0 percent but not more than 7.0 percent hydrogen peroxide, the available oxygen content (O a) is not more than 0.5 percent, when determined using the equation: O a = 16x = where for a material containing k species of organic peroxides:
Especially when in concentrated form, organic peroxides can decompose by self-oxidation, since organic peroxides contain both an oxidizer (the O-O bond) and fuel (C-H and C-C bonds). A "self-accelerating decomposition" occurs when the rate of peroxide decomposition generates heat at a faster rate than it can be dissipated to the environment ...
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Class 5.1, Oxidizing Substances, bears a black flaming 'O' symbol on a yellow background. Class 5.2, Organic Peroxides, bears a black or white flame symbol with the upper half of the placard having a red background and the lower half with a yellow background.
The peroxide group is marked in blue. R, R 1 and R 2 mark hydrocarbon moieties. The most common peroxide is hydrogen peroxide (H 2 O 2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well. In addition to hydrogen peroxide, some other major classes of ...
Organic peroxides – Organic substances which contain the bivalent –O–O– structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals Alternative sign. Division 5.2
When R is organic, the compounds are called organic hydroperoxides. Such compounds are a subset of organic peroxides , which have the formula ROOR. Organic hydroperoxides can either intentionally or unintentionally initiate explosive polymerisation in materials with unsaturated chemical bonds .
The oxidizing tendency of peroxides is related to the electronegativity of the substituents. Electrophilic peroxides are stronger oxygen-atom transfer agents. The oxygen-atom donor tendency correlates with the acidity of the O−H bond. Thus, the order of oxidizing power is CF 3 CO 3 H > CH 3 CO 3 H > H 2 O 2.
