✦ Synopsis

The oxidation of propanal has been studied below the ignition region. The nature and relative concentration of products depend on both the temperature and the fuel-oxygen ratio due to the alternative reactions for the propionyl radical:

C2Hs(~O(+M) -~ C2H 5. + CO(+M).

(4) The products are described in terms of the subsequent reactions of peroxypropionyl and ethyl radicals, which, in competition, lead to the formation of peroxypropionic acid and ethyl hydroperoxide. By using propanal-2,2-d 2, the mechanism of several reactions are elucidated; in particular, the formation of acetaldehyde.

Rate constants for the tunneling reaction, HD + D ~ H + D 2, in solid HD have been determined by using ESR in the very low temperature range of 2.6-6.5 K. The rate constants increase steeply with increasing temperature above 5 K, while they are almost independent of temperature below 5 K. The result

A photoinitiation technique has been used to study the gas-phase reactions of specific alkylperoxy radicals derived from azomethane and 2,3-dimethylbutane. The rate of production of radicals is controlled and measured at temperatures (~100°C), where the number of reactions is reduced so as to permit
