Chapter 3 The gas phase combustion of aldehydes

Detailed Chemical Kinetic Study of Acetaldehyde Oxidation and Its Interaction with NOx

“…Aldehydes, which are organic compounds containing a −CHO functional group, appear as one of the most important intermediates amidst the pyrolysis and oxidation of hydrocarbon fuels. For example, during the low-temperature oxidation pathway of alkanes, aldehydes are produced as key species in the preignition phase of hydrocarbon combustion. , In a recent work on diethyl ether (DEE) and dimethyl ether (DME) blends with ethanol, it was found that the formation of acetaldehyde as an intermediate was the key reason for the enhanced reactivity of the DEE/ethanol blend. A similar observation was made by Salooja , who observed aldehydes as the major intermediate species controlling the oxidation behavior of dialkyl ethers.…”

The cis- and trans-formylperoxy radical: fundamental vibrational frequencies and relative energies of the X̃ 2A′′ and à 2A′ states

“…In the early stages of the oxidative process, HCcO is formed from formaldehydeeither by photodissociation, or via reaction with a variety of open-shell species. [1][2][3][4][5] The nature of formyl radical reactivity is relevant to understanding atmospheric chemistry in polluted environments due to its liberation of Hc to yield CO and the reaction of HcCO with O 2 to furnish HO 2 c. The current research is concerned with characterization of the formylperoxy radical, an intermediate in the latter reaction, shown explicitly below (reaction (R1)). 2,4 HCcO + O 2 / [HC(O)OOc] / HO 2 c + CO (R1)…”
