Thus, organic peroxides are useful as initiators for some types of polymerization, such as the acrylic, unsaturated polyester, and vinyl ester resins used in glass-reinforced plastics. MEKP and benzoyl peroxide are commonly used for this purpose. However, the same property also means that organic peroxides can explosively combust.
Ascaridole was the first, and for a long time only, discovered naturally occurring organic peroxide.It was isolated from Chenopodium oil and named by Hüthig in 1908. He found that when heated to between 130° and 150 °C "there occurs, with sudden boiling in which the temperature momentarily rises to about 250°, a decomposition of an explosive character, occasionally accompanied by ignition.
Methyl ethyl ketone peroxide (MEKP) is an organic peroxide with the formula [(CH 3)(C 2 H 5)C(O 2 H)] 2 O 2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Benzoyl peroxide is a chemical compound (specifically, an organic peroxide) with structural formula (C 6 H 5 −C(=O)O−) 2, often abbreviated as (BzO) 2. In terms of its structure, the molecule can be described as two benzoyl ( C 6 H 5 −C(=O)− , Bz) groups connected by a peroxide ( −O−O− ).
Compound I then oxidizes an organic substrate to give a substrate radical [2] and Compound II, which can then oxidize a second substrate molecule. Haem peroxidases include two superfamilies: one found in bacteria, fungi, and plants, and the second found in animals. The first one can be viewed as consisting of 3 major classes: [3]
