Abstract

The reflected shock tube technique with a novel multi-pass absorption spectrometric detection method was used used to study reactions of OH radicals: OH + OH → H 2O + O (1), OH + H 2 → H 2O + H (2), OH + C 2H 6 → H 2O + C 2H 5 (3), OH + CH 31CH 2 + H 2O (4), and OH + CH 2 → CH 2O + H (5). The measurements were performed in single-shot experiments with low initial concentrations of hydroxyl radicals, [OH] 0 = (5-15) ×10 12 molecule/cc, which allowed reliable isolation of the elementary reactions. The measured rate constants were: k 1 = 5.2 × 10 -12 (at 1504 K) and 4.6 × 10 -12 (at 1545 K); k 2 = 5.44 × 10 -11 exp(∼ 3220 K/T) (832-1359 K), k 3 = 1.10 × 10 -10 exp(∼ 2537 K/T) (822-1367 K), k 4 = 1.72 x 10 -11 exp(926 K/T) (834-2383 K), and k 5 = (3.0 ± 2.4) × 10 -11 (1841-2324 K) (all in cc/molecule-sec). This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
