Oxidation of isobutyraldehyde in aged boric-acid-coated vessels

Abstract

The oxidation of (CH3)2CHCH0 has been studied over a wide range of mixture composition at 440°C in an aged boric-acid-coated vessel. By the use of the pressure against time profiles, rate constants kl = 0.120f0.010 dm3 mol-'s-' and k4 = (1.83 kO.10) x lo6 dm3 mol-l s'l have been obtained.

Kinetics of the reactions of hydroxyl radicals with aldehydes studied under atmospheric conditions

“…Abstraction of hydrogen from the alkyl group of the aldehydes will become more significant as the C-H bonds become weaker in going from primary to secondary to tertiary and as the number of C-H bonds increase. Direct evidence for hydroxyl attack on both parts of the aldehyde molecule comes from a study of the products of the oxidation of isobutyraldehyde at 713 K (21).…”

Kinetics of Hydrogen-Oxygen and Hydrocarbon-Oxygen Reactions.

“…From measurements of the trace amounts of butane formed by reaction (15) 14is considered to proceed by a peroxy radical isomerisation and decomposition process, represented by equations (16)- (18).…”

“…It was hoped that alkoxy radicals might be produced by reaction (18), so that their behaviour could be investigated, but no evidence for this reaction has been found. Dr. Walker has been invited to give a paper on "Recent Progress in Gas-phase Hydrocarbon Oxidation Chemistry" at a two-day meeting of…”
