Abstract
- Smog chamber relative rate techniques were used to measure rate coefficients of (5.00 ± 0.54) × 10<superscript>-11</superscript>, (5.87 ± 0.63) × 10<superscript>-11</superscript>, and (6.49 ± 0.82) × 10<superscript>-11</superscript> cm<superscript>3</superscript> molecule<superscript>-1</superscript> s<superscript>-1</superscript> in 700 Torr air at 296 ± 1 K for reactions of OH radicals with allyl alcohol, 1-buten-3-ol, and 2-methyl-3-buten-2-ol, respectively; the quoted uncertainties encompass the extremes of determinations using two different reference compounds. The OH-initiated oxidation of allyl alcohol in the presence of NO<subscript>x</subscript> gives glycolaldehyde in a molar yield of 0.85 ± 0.08; the quoted uncertainty is two standard deviations. Oxidation of 2-methyl-3-buten-2-ol gives acetone and glycolaldehyde in molar yields of 0.66 ± 0.06 and 0.56 ± 0.05, respectively. The reaction of OH radicals with allyl alcohol, 1-buten-3-ol, and 2-methyl-3-buten-2-ol proceeds predominately via addition to the >C&dbond;CH<subscript>2</subscript> double bond with most of the addition occurring to the terminal carbon. © 2010 Wiley Periodicals, Inc.
