Gas-Phase Kinetic Investigation of the OH-Initiated Oxidation of a Series of Methyl-Butenols under Simulated Atmospheric Conditions.

ABSTRACT: Five biogenic unsaturated alcohols have been investigated under simulated atmospheric conditions regarding their gas-phase OH reactivity. The gas-phase rate coefficients of OH radicals with 2-methyl-3-buten-2-ol (k₁), 3-methyl-2-buten-1-ol (k₂), 3-methyl-3-buten-1-ol (k₃), 2-methyl-3-buten-1-ol (k₄), and 3-methyl-3-buten-2-ol (k₅) at 298 ± 2 K and 1000 ± 10 mbar total pressure of synthetic air were determined under low- and high-NO_x conditions using the relative kinetic technique. The present work provides for the first time the rate coefficients of gas-phase reactions of hydroxyl radicals with 2-methyl-3-buten-1-ol and 3-methyl-3-buten-2-ol. The following rate constants were measure
