Autoignition of heptanes; experiments and modeling
International Journal of Chemical Kinetics - Tập 37 Số 12 - Trang 728-736 - 2005
J. M. Smith, John M. Simmie, Henry J. Curran
AbstractThere is much interest in determining the influence of molecular structure on the rate of combustion of hydrocarbons; the C7H16 isomers of heptane have been selected here as they exemplify all the different structural elements present in aliphatic, noncyclic hydrocarbons.With the exception of ... hiện toàn bộ
A high‐temperature chemical kinetic model for primary reference fuels
International Journal of Chemical Kinetics - Tập 39 Số 7 - Trang 399-414 - 2007
Marcos Chaos, Andrei F. Kazakov, Zhenwei Zhao, Frederick L. Dryer
AbstractA chemical kinetic mechanism has been developed to describe the high‐temperature oxidation and pyrolysis of n‐heptane, iso‐octane, and their mixtures. An approach previously developed by this laboratory was used here to partially reduce the mechanism while maintaining a desired level of detailed reaction...... hiện toàn bộ
Shock tube measurements of branched alkane ignition times and OH concentration time histories
International Journal of Chemical Kinetics - Tập 36 Số 2 - Trang 67-78 - 2004
Matthew A. Oehlschlaeger, David F. Davidson, John T. Herbon, Ronald K. Hanson
AbstractIgnition times and hydroxyl (OH) radical concentration time histories were measured behind reflected shock waves during the oxidation of three branched alkanes: iso‐butane (2‐methylpropane), iso‐pentane (2‐methylbutane), and iso‐octane (2,2,4‐trimethylpentane). Initial reflected shock conditions ranged from 1177 to 2009 K and 1.10 to 12.58 atm with dilute f...... hiện toàn bộ
Kinetics and mechanism for the oxidation of 1,1,1‐trichloroethane
International Journal of Chemical Kinetics - Tập 22 Số 6 - Trang 577-590 - 1990
Linda Nelson, Imelda Shanahan, Howard Sidebottom, Jack Treacy, Ole John Nielsen
AbstractThe reaction mechanisms for oxidation of CH3CCl2 and CCl3CH2 radicals, formed in the atmospheric degradation of CH3CCl3 have been elucidated. The primary oxidation products from these radicals are CH3CClO and CCl...... hiện toàn bộ
The flash photolysis—shock tube technique using atomic resonance absorption for kinetic studies at high temperatures
International Journal of Chemical Kinetics - Tập 17 Số 3 - Trang 315-326 - 1985
J. V. Michael, John W. Sutherland, Rosemarie Klemm
AbstractA flash photolysis‐shock tube technique is described for making kinetic measurements at high temperature. Coupled with sensitive atomic resonance absorption detection, this method allows bimolecular rate constants for atom‐molecule reactions to be measured directly under conditions free from kinetic complications. Experiments were performed in the reflected...... hiện toàn bộ
Nickel peroxide: A more probable intermediate in the Ni(II)‐catalyzed decomposition of peroxomonosulfate
International Journal of Chemical Kinetics - Tập 39 Số 6 - Trang 320-327 - 2007
P. Thendral, S. Shailaja, M. Ramachandran
AbstractThe Ni(II) ion catalyzed thermal decomposition of peroxomonosulfate (PMS) was studied in the pH range 3.42–5.89. The rate is first order in [PMS] and Ni(II) ion concentrations. At pH greater than or equal to 5.23, the reaction becomes zero order in [PMS] and this changeover in the order of the reaction occurs at a higher concentration of nickel ions. The fi...... hiện toàn bộ
A pyrolysis mechanism for ammonia
International Journal of Chemical Kinetics - Tập 22 Số 5 - Trang 513-535 - 1990
David F. Davidson, Katharina Kohse‐Höinghaus, Albert Y. Chang, Ronald K. Hanson
AbstractThe mechanism of NH3 pyrolysis was investigated over a wide range of conditions behind reflected shock waves. Quantitative time‐history measurements of the species NH and NH2 were made using narrow‐linewidth laser absorption. These records were used to establish an improved model mechanism for ammonia pyrolysis. The...... hiện toàn bộ
Constant time interval method for analysis of reaction rate data
International Journal of Chemical Kinetics - Tập 5 Số 4 - Trang 577-582 - 1973
Norman E. Shank
AbstractIn the study of chemical kinetics, many integrated reaction rate equations have the form In [f(A) + a] = bt + c, where a, b, and c are constants and f... hiện toàn bộ
Kinetic and mechanistic aspects of the NO oxidation by O2 in aqueous phase
International Journal of Chemical Kinetics - Tập 26 Số 12 - Trang 1207-1227 - 1994
Marçlal Pires, Michel J. Rossi, David S. Ross
AbstractThe oxidation kinetics of NO by O2 in aqueous solution was observed using a stopped flow apparatus. The kinetics follows a third order rate law of the form k · [NO]2 · [O2] in analogy to gas‐phase results. The rate constant at 296 K was measured as (6.4 ± 0.8) · 10... hiện toàn bộ
