FTIR gas kinetic study of the reactions of ozone with a series of hexenols at atmospheric pressure and 298 K
Relative rate coefficients of the reactions of O-3 with (Z)-3-hexen-1-ol, (E)-3-hexen-1-ol and (E)-2-hexen-1-ol have been determined in an environmental chamber with in situ FTIR detection of the reactants at 298 K and 760 Torr. The following rate coefficients (in units of 10(-17) cm(3) molecule(-1) s(-1)) have been determined: (6.04 +/- 0.95) for (Z)-CH2(OH)CH2CH=CHCH2CH3; (5.83 +/- 0.86) for (E)-CH2( OH)CH2CH=CHCH2CH3; (5.98 +/- 0.73) for (E)-CH2(OH)CH=CH(CH2)(2)CH3. This is the first kinetic study for the reactions of O-3 with (E)-2-hexen-1-ol and (E)-3-hexen-1-ol. Reactivity trends are developed and the atmospheric persistence of these compounds is calculated based on the rate coefficients. (C) 2014 Elsevier B.V. All rights reserved.
