Abstract

We have carried out relative rate experiments (T = 294 ± 2 K, atmospheric pressure) to investigate the OH‐oxidation of o‐, m‐, and p‐ethyltoluene and n‐nonane (k~1~, k~2~, k~3~, and k~4~ respectively). The experiments were performed in a 2‐m^3^ smog chamber with Teflon coated walls. The rate constants obtained are (in cm^3^ molecule^−1^ s^−1^ with two sigma uncertainties): k~1~ = (1.36 ± 0.07) × 10^−11^; k~2~ = (2.12 ± 0.26) × 10^−11^; k~3~ = (1.47 ± 0.04) × 10^−11^, and k~4~ = (0.95 ± 0.02) × 10^−11^. The measured rate constants are in accordance with previously published data, so that a coherent group of values for the compounds studied can be established. Atmospheric implications, ozone, and particle production are discussed. In addition, we have determined the amount of o‐, m‐, and p‐ethyltoluenes in different types of gasoline. © 2004 Wiley Periodicals, Inc. Int J Chem Kinet 36: 367–378 2004
