Oxide and organic peroxide signs
An organic compound containing -O-O-peroxy functional group formed by replacing hydrogen atoms in hydrogen peroxide with an organic group such as an alkyl group, an acyl group, an aromatic group or the like. Characterized by heating more than a certain temperature will decompose to produce oxygen free radicals, unstable, easy to break down. Chemical production of organic peroxides is mainly used for synthetic resin polymerization initiator, catalyst. In the field of polymer materials, it can be used as a radical polymerization initiator, graft reaction initiator, rubber and plastic cross-linking agent, unsaturated polyester curing agent and spinning grade polypropylene in the preparation of molecular weight and Molecular weight distribution regulator. Environmental pollution in the air under the action of light through the free radical reaction can produce peroxy nitrates compounds, photochemical oxidants in one of the species. On the skin, eyes, mucous membrane has a strong irritant, is an important pollutant in the atmosphere. Such substances are flammable and explosive dangerous goods, the use should pay attention to safety. Generally, the active oxygen content, activation energy, half-life and decomposition temperature were used as the basis of selection.
Broad oxide (oxide) refers to the oxygen element and another chemical composition of the binary compounds, such as carbon dioxide (CO?), Calcium oxide (CaO) and so on. But the combination of oxygen and electronegativity with greater fluoride is generally referred to as fluoride rather than oxide.
