    The reaction of atomic oxygen O(3P) with propane (1981)

    Notes: The reaction of O(3P) atoms with propanehas been studied at temperatures near 300 K by using a discharge flow system. Oxygen atoms were generated in the absence of molecular oxygen by the reaction N + NO → N2 + O, nitrogen atoms having been generated in a microwave discharge. Rate constants for the reaction were measured in two ways, either by measurement of O-atom decay in the presence of excess propane or by measuring the change in propane concentration after an appropriate time in the presence of an excess of oxygen atoms. The two methods were in good agreement, and the mean rate constant at 306 K is given by \documentclass{article}\pagestyle{empty}\begin{document}$$ k_1 = (4.7 \pm 0.8) \times 10^6 {\rm dm}^3 /{\rm mol}\;\sec $$\end{document} A study of the products of the reaction under conditions corresponding to complete removal of oxygen atoms has shown that an important product of the reaction in the early stages is propene. This is difficult to explain interms of a mechanism involving alkoxy radicals similar to that which has been proposed for some other O(3P)-hydrocarbon reactions. An alternative mechanism is proposed in terms of successive hydrogen abstraction reactions.

    Production and decomposition of highly excited 2-butyl radicals by the addition of hot hydrogen atoms to but-2-ene. Cross section for the addition reaction (1988)
    New York, NY : Wiley-Blackwell

    Notes: Highly excited 2-butyl radicals have been generated by addition of hot hydrogen atoms to but-2-ene. Atoms of initial energy 130 kJ mol-1 and 161 kJ mol-1 were produced by photolysis of H2S. Rates of decomposition of the highly excited 2-butyl radicals were monitored by analysis of stabilization and decomposition products, and the extent of energy-loss of the hydrogen atoms in nonreactive collisions assessed by measuring the effect of added xenon on product yields. A model involving the cross-section for the addition reaction, energy transfer in nonreactive collisions between hydrogen atoms and but-2-ene, RRKM rate constants for decomposition of excited 2-butyl radicals, and collisional energy transfer from the radicals, has been used to calculate product yields for comparison with experimental values. It is concluded that the cross-section for addition of hydrogen atoms of energy about 130 kJ mol-1 to but-2-ene is 0.055 ± 0.028 nm2. This value is compatible with the A factor for the thermal addition reaction.

    Reaction of hot H atoms with CD3Br (1984)
    New York, NY : Wiley-Blackwell

    Notes: Energetic H atoms produced by photolysis of gaseous HI react with CD3Br by D abstraction (1) and Br abstraction (2) and possibly also by the substitution reactions (4) and (5). Yields of HD and CD3H have been determined for several defined initial translational energies of H*. The phenomenological threshold energy of reaction (1) is 53 ± 5 kJ/mol. Over the range of initial energies of 76-109 kJ mol the integral probability of reaction (1) increases substantially, but the sum of the integral probabilities of reactions (2) and (5) shows little change. The ratio of the sum of the integral yields of reactions (2) and (5) to the integral yield of reaction (1), when normalized to equal numbers of Br and D atoms, is 69 ± 33 at an initial energy of 76 kJ/mol and 31 ± 6 at 109 kJ/mol.

    The reaction of atomic oxygen O(3P) with isobutane (1982)

    Notes: The reaction of O(3P) atoms with isobutane has been studied by using the discharge-flow system described previously [1]. The rate constant was measured from determinations of the isobutane concentration in the presence of an excess of O atoms and is given by k1 = (7.9 ± 1.4) × 107 dm3/mol·s at 307 K. In order to explain the observed reaction products, the mechanism requires that the principal process be the successive abstraction of H atoms from isobutane and from the t-butyl radical to give isobutene. A minor part of the reaction between O(3P) and the t-butyl radical gives the t-butoxy radical, which decomposes to acetone. The branching ratios are .

    Reaction of hot H atoms with CDCl3 (1982)

    Notes: Energetic hydrogen atoms generated by photolysis of HBr or HI react with CDCl3 by abstracting either a deuterium atom (1) or a chlorine atom (2): The integral probability of reaction (2) has been measured for several defined initial translational energies of H*, and the phenomenological threshold energy is 31 ± 14 kJ/mol. For initial translational energies in the range of 66-121 kJ/mol, the ratio of the integral probabilities of Cl abstraction and of D abstraction, when normalized to equal numbers of Cl and D atoms, is 2.4 ± 0.3. The interpretation of the integral reaction probabilities in terms of the excitation functions of reactions (1) and (2) is discussed. Measurements of the moderating effect of CO2 on reactions (1) and (2) show that CDCl3 is slightly more effective than CO2 as a moderator of H atoms in the energy range of 90-30 kJ/mol.

    Notes: The rate constants for the gas-phase reactions between methylethylether and hydroxyl radicals (OH) and methylethylether and chlorine atoms (Cl) have been determined over the temperature range 274-345 K using a relative rate technique. In this range the rate constants vary little with temperature and average values of kMEE+OH = (6.60-2.62+3.88) × 10-12 cm3 molecule-1 s-1 and kMEE+Cl= (34.9 ± 6.7) × 10-11 cm3 molecule-1 s-1 were obtained. The atmospheric lifetimes of methylethylether have been estimated with respect to removal by OH radicals and Cl atoms to be ca. 2 days and ca. 30-40 days, respectively. © 1997 John Wiley & Sons, Inc.
