Kinetics of HO 2 + HO 2 ! H 2 O 2 + O 2 : Implications for Stratospheric H

[1] The reaction HO2 + HO2 ! H2O2 + O2 (1) has been studied at 100 Torr and 222 K to 295 K. Experiments employing photolysis of Cl2/CH3OH/O2/N2 and F2/H2/O2/N2 gas mixtures to produce HO2 confirmed that methanol enhanced the observed reaction rate. At 100 Torr, zero methanol, k1 = (8.8 ± 0.9) 10 13 exp[(210 ± 26)/T] cm molecule 1 s 1 (2s uncertainties), which agrees with current recommendations...

Quasiclassical Trajectory Study of the Environmental Reaction O + HO

We report a detailed dynamics and kinetics study of the title reaction over the range of translational energies 0.418 e Etr/kJ mol-1 e 62.760 by employing the quasiclassical trajectory method and a recently reported double many-body expansion potential energy surface for ground-state HO3. A comparison of the calculated thermal rate constants with the available experimental results is also prese...

Reaction of HO with hydroxyacetone (HOCH2C(O)CH3): rate coefficients (233-363 K) and mechanism.

Absolute rate coefficients for the title reaction, HO + HOCH(2)C(O)CH(3)--> products (R1) were measured over the temperature range 233-363 K using the technique of pulsed laser photolytic generation of the HO radical coupled to detection by pulsed laser induced fluorescence. The rate coefficient displays a slight negative temperature dependence, which is described by: k(1)(233-363 K) = (2.15 +/...

Liquid-Liquid Equilibrium for the Ternary Systems of Solvent+ m/o/p-Cresol+Water: Thermodynamic Modeling

In this study, NRTL and UNIQUAC thermodynamic models were used to predict the composition of ternary mixtures of solvents+ m/o/p-cresol+ water in organic and aqueous phases. Various solvents are used for the separation of cresols from water. In this study, methyl propyl ketone, methyl isopropyl ketone, methyl butyl ketone, and methyl isobutyl ketone solvents were investigated. Intermolecular in...
