The Kinetics of the Oxidation of Gaseous Propionaldehyde.

Organic Peracids.

“…The same catalysts are suitable, and the same precautions must be observed (dry oxygen, absence of manganese salts, etc.). Steacie and coworkers (497) studied the oxygen oxidation of propionaldehyde at 120-170°C. and reported that perpropionic acid is formed as an intermediate, although it was not isolated.…”

The Presence of Free Radicals in the Thermal Decomposition of Diethyl Ether

“…In confirmation of this, we have found that small amounts are very effective in promoting the chain decomposition of other compounds,2 and can be used to initiate chain reactions from 400 to 450°, just as azometbane has been used around 300°. 8 The catalysis of acetaldehyde by ethylene oxide is of special interest, firstly, as it is formed from ethylene oxide by isomerization and so any investigations on the decomposition of ethylene oxide must necessarily consider the chain decomposition of acetaldehyde, and secondly, because the kinetics are simplified by the fact that only one type of radical, the methyl radical, need be considered.…”

The kinetics of oxidation of benzaldehyde. II. The kinetics of the uncatalyzed reaction in solution

“…The kinetic properties of the gas-phase reaction (mainly of acetaldehyde), however, are reasonably well known (cf. Bodenstein 19310,6;Hatcher, Steacie & Howland 1932;Pease 1933;Steacie, Hatcher & Rosenberg 1934;McDowell & Thomas 1949;Askey 1930). These are different from expectation based on the reaction mechanism of Boiland & Gee (1946) and Bolland (1949) which, on the other hand, is the mechanism of the reaction initiated by light both in the liquid and gas phase (Bowen & Tietz 1930;Cooper & Melville 1951).…”
