A Shock Tube Study of the Reactions of the Hydroxyl Radical with
Several Combustion Species
Int. J. Chem. Kinet. 1991, 23, 1075.
Abstract
Reactions of the hydroxyl radical, OH, with several organic species of interest
in combustion chemistry have been studied near 1200 K and 1 atm in shock tube
experiments in which UV absorption was used to monitor the OH concentration. Rate
coefficients were measured for the reactions of OH with 2,3-dimethylbutane,
isooctane, neooctane, ethylene, propylene, acetylene, formaldehyde, methanol, and
ethanol. The values were found to be (in units of 1E+12 cm3/mol s): 21, 22, 18,
2.6, 9.6, 0.28, 12, 5.2, and 5.3. These measured values are compared with
previous experimental results and, where appropriate, transition-state theory
calculations.
