Effect of formic acid and formates on the oxidation of hydrocarbons and hydrocarbon polymers In order to ascertain the nature of the inhibiting action of the products of hydrocarbon oxidation, a kinetic study was made of the oxidation of cetane, a hydrocarbon serving as a model of the polyethylene chain, at –°C. AUTOXIDATION. A second method is to use molecular oxygen as oxidant and to initiate an autoxidation reaction by using a metal ion which will readily undergo a one electron oxidation. Among the former reagents, two commonly used compounds are the potassium salts of the dichromate and permanganate : D. M. Roundhill.
Hydrocarbons, the essential component of petroleum-based fuels, are likely during storage to react with atmospheric oxygen and with one another. Products which originate from oxygenation will undergo further changes, resulting in change of coloration, the presence of non-volatile, macromolecular substances (gum), Cited by: 2. Polyolefin, any of a class of synthetic resins prepared by the polymerization of olefins. Olefins are hydrocarbons (compounds containing hydrogen [H] and carbon [C]) whose molecules contain a pair of carbon atoms linked together by a double bond. They are most often derived from natural gas or from.
Cobalt acetate bromide in acetic acid solution is an extraordinarily active catalyst for the autoxidation of hydrocarbons. Carboxylic acids and ketones are readily prepared in high yields at moderate temperatures and at atmospheric pressure. In addition, benzylic and allylic groups can be converted Cited by: PDF ( K) PDF-Plus ( K) Citing articles; Absolute rate constants for hydrocarbon autoxidation. XIII.

Autoxidation (auto-oxidation) is a complex oxidation mechanism that proceeds through a free radical chain process.
It is a common degradation mechanism for unsaturated fats, but a number of drugs containing carbon–carbon double bonds also undergo autoxidation. On the autoaccelerated character of the branched oxidation of polyolefins. Macromolecular Symposia(1), DOI: /masy John Scheirs, Stephen W.

The role of peroxides in the kinetics of liquid-phase oxidation processes is then considered, along with several elementary stages of the liquid-phase Book Edition: 1. Autoxidation, the free radical chain reaction that nominally inserts O 2 into hydrocarbons to give peroxides, is primarily responsible for the degradation of all organic materials.
Peroxyl radicals propagate autoxidation mainly by abstraction of labile H-atoms from the hydrocarbons, whereas radical-trapping antioxidants (RTAs) Cited by: 6.
Autoxidation. Autoxidation is a chain reaction, starting with the formation of a free radical (initiation), continuing with the propagation of the reaction with the formation of more and more free radicals and unstable molecules and ending with reactions between the free radicals to form stable molecules (termination).
Abstract. The oxidation and autoxidation of adamantane, norbornane and cyclohexane can be photochemically promoted by ceric ammonium nitrate in acetonitrile at room temperature, both processes being extremely efficient and selective with adamantane.

Under some specific conditions it can, however, be used as a synthetic method. Oxidation of cyclohexane at TiO 2, studied by Almquist and Biswas, 25 is a good example of such a process.

induction stage. Autoxidation, or air oxidation, is one of the simplest functionalization reactions of alkanes. In general, hydroperoxides are the first-formed products, but these can decompose under the conditions of the reaction to give the ketone and alcohol. 78 The reagents used to initiate the reaction are usually O -centered radicals or even O 2 itself.
