Shock tube study of OH reactions with linear hydrocarbons near 1100 K

Abstract

Reactions of the hydroxyl radical with several linear hydrocarbon species occurring in combustion chemistry have been considered at temperatures near 1100 K and 1 atmosphere in shock tube experiments. The OH density was monitored using 310 nm UV absorption of the A2Σ+ (SINGLEBOND) X 2Π transition. Rate coefficients for the reaction of OH with ethane (8.37 × 10−12 cm3 molecule−1 s− 1; 970 K), hexane (2.18 × 10−11; 962 K), heptane (3.34 × 10−11, 1186 K), octane (4.42 × 10−11; 1078 K), nonane (4.55 × 10−11; 1097 K), and decane (5.64 × 10−11; 1109 K) have been determined. These values are compared with previous experimental results and transition state theory calculations. © 1996 John Wiley & Sons, Inc.
