Autoxidation is any oxidation that occurs in open air or in presence of oxygen and/or UV radiation and forms peroxides and hydroperoxides. A classic example of autoxidation is that of simple ethers like diethyl ether whose peroxides can be dangerously explosive. The most fundamental reactions in chemistry are the redox processes. ... General Name, Symbol, Number oxygen, O, 8 Chemical series Nonmetals, chalcogens Group, Period, Block 16, 2, p Appearance colorless (gas) very pale blue (liquid) Atomic mass 15. ... Note: Ultraviolet is also the name of a 1998 UK television miniseries about vampires. ... Peroxide has three distinct meanings: // Main article: hydrogen peroxide In common usage, peroxide is an aqueous solution of hydrogen peroxide (HOOH or H2O2) sold for use as a disinfectant or mild bleach. ... Organic peroxides are organic molecules containing the peroxide functional group ROOR If the R is hydrogen, the compound is called organic hydroperoxide. ... Ether is the general name for a class of chemical compounds which contain an ether group — an oxygen atom connected to two (substituted) alkyl groups. ... Diethyl ether, also known as ether and ethoxyethane, is a clear, colorless, and highly flammable liquid with a low boiling point and a characteristic smell. ...
Reactions of importance include: hydrolysis, saponification, reduction and autoxidation.
Autoxidation of polyunsaturated lipids involves a free radical chain reaction that is most frequently initiated by exposure of lipids to light, ionisation radiation, metal ions and metalloprotein catalysts.
Accelerated methods to induce autoxidation and photoxidation of the oils and to evaluate antioxidant activity were adapted from Tsaknis, (1996).
During thermal autoxidation in the dark, (Oven heating and Rancimat), radical autoxidation occurs when hydroperoxides and peroxides are breaking down and generating more free radicals to maintain the chain reaction.
