Abstract

Mixtures of hydrocarbons (methane, allene, propyne, propene, and propane)–H~2~–O~2~ highly diluted with argon were heated to a temperature ranging from 1200 to 1900 K behind reflected shock waves, and the additive effects of methane, allene, propyne, propene, and propane on OH radical production in H~2~ oxidation were studied by observing time‐resolved UV‐absorption (306.7 nm). It was found that, in H~2~ oxidation below 1500 K, the addition of these hydrocarbons prolonged the delay time of the onset of the rapid OH radical production. An analysis using reported kinetic modeling of C~1~–C~4~ oxidation gave valuable information for reactions between hydrocarbons and H, O atoms and OH radicals. Β© 2004 Wiley Periodicals, Inc.
