A study of the thermal decomposition of allyl t-butyl peroxide and 3-hydroperoxy-1-propene (allyl hydroperoxide) in toluene /|nby Krishnankutty Nair V. G. -- 260 St. Catharines [Ont. : s. n.],
… of decomposition were lowered in presence of the radical trap~methyl styrene. By the radical trap method, the induced decomposition at 1300 is shown to be 12.5%. From the yield of 4-phenyl-l,2- epoxy butane the major path of induced decomposition is shown to be via an addition mechanism. On the …

The kinetics and induced decomposition on the thermal decomposition of hydroperoxides /
… 20 to 28 K cal/mole, Styrene was used as a free radical trap to inhibit the induced decomposition. The results permitted calculation of how much induced decomposition occurred in its absence. The experimental resvilts indicate that the induced decomposition is important for t-butyl hydroperoxide …

The Antioxidant Function of Dithiophosphoryl Compounds in Rubbers
… during fatiguing and the corresponding sulphinyl radical acts as an alkyl radical trap. Ultraviolet spectroscopic analysis showed the formation of conjugated diene and triene supporting the above mechanism.

Thermo-analytical and physico-chemical characterisation of organoclays and polymer-clay nacomposites.
… a current theory that structural iron acts as a radical trap. This is thought to significantly reduce the catalytic activity of the clay's acid sites until higher temperatures. The formulation of polystyrene-clay nanocomposites (PSCNs) by in-situ polymerisation led to various results pertaining …

Implications of Advanced Glycation Endproducts in Oxidative Stress and Neurodegenerative Disorders
… activated microglia secrete cytokines and free radicals, including nitric oxide (NO). Roles proposed for NO in the pathophysiology of the central nervous system are increasingly diverse and range from intercellular signaling, through necrosis of cells and invading pathogens, to the involvement …

Studies on the structure, function and mechanisms of the cbb3 type cytochrome c oxidase from Vibrio cholerae and the cytochrome bo3 ubiquinol oxidase from Escherichia coli
… the first adduct intermediate (A) decays into a radical intermediate (PM). It’s a four electron reduction of O2 in which two electrons comes from Fe2+, another from Cu+ and the source of fourth electron is still under debate. Injection of the first electron from electron donor will transform this …

A Radical Approach to Syntheses and Mechanisms
The critically important nature of radical and radical ion mechanisms in biology and chemistry continues to be recognized as our understanding of these unique transient species grows. The work presented herein demonstrates the versatility of kinetic studies for understanding the elementary chemical …
