Research Abstract

The kinetics ofα-hydroxyethyl radical with molecular oxygen has been studied by laser photolysis/near-IR wavelength modulation spectroscopy and quantum chemical calculation with RRKM/master equation analysis. Theoretically estimated rate constants were well agreed with those of experiments, showing slightly negative temperature dependence. The theoretical calculation indicates that the main product of the reaction were acetaldehyde and HO_2 below 100 atm, and the stabilization to CH_3CH(OH) O_2 were competed at higher pressure.
