    The reaction of OH radicals with dimethyl sulfide (1986)

    Notes: The kinetics of the gas phase reaction of OH radicals with dimethyl sulfide (CH3SCH3) have been studied at various temperatures and total pressures using two relative rate methods and a flash photolysis technique. For the relative rate methods, rate constants were measured at 296 ± 2 K as a function of the O2 pressure at a total pressure of ca. 740 torr. Data from these three experimental techniques were not in agreement. It is concluded that the relative rate techniques are subject to secondary reactions, possibly involving CH3S radicals. A rate constant of (2.5-0.6+0.9) × 10-12 e(130 = 102)/T cm3 molecule-1 s-1 obtained using the flash photolysis-resonance fluorescence data in the absence of O2, and which is in agreement with the lower range of values previously reported in the literature, is recommended.

    Kinetics of the reactions of naphthalene, 2-methylnaphthalene, and 2,3-dimethylnaphthalene with OH radicals and with O3 at 295 ± 1 K (1986)

    Notes: The kinetics of the gas-phase reactions of naphthalene, 2-methylnaphthalene, and 2,3-dimethylnaphthalene with O3 and with OH radicals have been studied at 295 ± 1 K in one atmosphere of air. Upper limit rate constants for the O3 reactions of 〈3 × 10-19, 〈4 × 10-19, and 〈4 × 10-19 cm3 molecule-1 s-1 were obtained for naphthalene, 2-methylnaphthalene, and 2,3-dimethylnaphthalene, respectively. For the OH radical reactions, rate constants of (in units of 10-11 cm3 molecule-1 s-1) 2.59 ± 0.24, 5.23 ± 0.42, and 7.68 ± 0.48 were determined for naphthalene, 2±methylnaphthalene, and 2,3-dimethylnaphthalene, respectively. These data show that under atmospheric conditions these naphthalenes will react mainly with the OH radical, with life-times due to this reaction ranging from ca. 11 h for naphthalene to ca. 4 h for 2,3-dimethylnaphthalene.

    Rate constants for the gas-phase reactions of the OH radical with a series of monoterpenes at 294 ± 1 K (1986)

    Notes: Using a relative rate technique, rate constants for the gas-phase reactions of the OH radical with a series of monoterpenes have been determined in one atmosphere of air at 294 ± 1 K. Relative to a rate constant for the reaction of OH radicals with 2,3-dimethyl-2-butene of 1.12 × 10-10 cm3 molecule-1 sec-1, the rate constants obtained were (in units of 10-11 cm3 molecule-1 sec-1): α-Pinene, 5.45 ± 0.32; β-pinene, 7.95 ± 0.52; Δ3-carene, 8.70 ± 0.43; d-limonene, 16.9 ± 0.5; α-terpinene, 36.0 ± 4.0; γ-terpinene, 17.6 ± 1.8; α-phellandrene, 31.0 ± 7.1; myrcene, 21.3 ± 1.6; and ocimene (acis-, trans-mixture), 25.0 ± 1.9. These are the first quantitative kinetic data reported for many of these monoterpenes. The rate constants obtained are compared with the available literature data and with a priori estimates based on the number and configuration of substituents around the double bond(s). The tropospheric lifetimes of these monoterpenes with OH radicals, NO3 radicals and O3 are estimated and compared. Atmospheric lifetimes with respect to reaction with the OH radical are calculated to range from ∼0.75 hr for α-terpinene to ∼5 hr for α-pinene.
