“…The inhibiting effect of bromine species has also been observed at lower temperatures in batch reactor [20,21] and flow reactor [22] experiments. However, static reactor experiments have shown that hydrogen bromide acts to catalyze the slow oxidation of hydrocarbons [5,[23][24][25][26][27][28][29].…”

The high-temperature bromine chemistry was updated and the inhibition mechanisms involving HBr and Br 2 were re-examined. The thermochemistry of the bromine species was obtained using the Active Thermochemical Tables (ATcT) approach, resulting in improved data for, among others, Br, HBr, HOBr and BrO. Ab initio calculations were used to obtain rate coefficients for selected reactions of HBr and HOBr, and the hydrogen/bromine/oxygen reaction mechanism was updated. The resulting model was validated against selected experimental data from literature and used to analyze the effect of HBr and Br 2 on laminar, premixed hydrogen flames. Our work shows that hydrogen bromide and molecular bromine act differently as inhibitors in flames. For HBr, the reaction HBr + H ⇀ ↽ H 2 + Br (R2) is rapidly equilibrated, depleting HBr in favor of atomic Br, which is the major bromine species throughout the reaction zone. The chain-breaking

“…It is seen from Table I that the bromophenols actually predominate over phenol itself. The experimental procedure was that described under "Apparatus" in the second paper of this series (3). The condensable effluent product from toluene oxidation, as well as those from ethylbenzene and cumene, was worked up by first extracting with strong sodium hydroxide solution.…”

“…Thus, in the ease of isopentane, acetone and acetic acid are produced (S). Similarly, the oxidation of 2,3dimethylbutane produces acetone and isopropyl alcohol (3). In passing to the oxidations of the individual aromatic compounds, it should be mentioned that experiments have shown that benzene is very resistant to hydrogen bromide-catalyzed oxidation; efforts to oxidize it at temperatures even as high as 250°C.…”

“…An example of reaction 20, hydro peroxide formation, is found in the gas-phase oxidation of isobutane, with HBr as the hydrogen donor (94). The reverse reaction has been detected in the pyrolysis of tert-butyl deuteroperoxide (95), by the formation of deu teromethane.…”

Since scientific papers which could be catalogued as reaction kinetics are currently being published at a rate of more than a thousand per year, a simple bibliography of one year's pUblications would fill the space allotted this review. Fortunately for the reviewer, many papers fall into special fields such as photochemistry, polymerization, contact catalysis, isotopic studies, or biochemical kinetics, which will be reviewed separately in the present volume or succeeding volumes of the Annual Review of Physical Chemistry.
