Author(s):   Zhang, Y.-X.; Bauer, S.H.
Title:   The Gas-Phase Pyrolysis of 2,2-Dinitropropane: Shock-Tube Kinetics
Journal:   J. Phys. Chem. A
Volume:   104
Page(s):   1217 - 1225
Year:   2000
Reference type:   Journal article
Squib:   2000ZHA/BAU1217-1225

Reaction:   (CH3)2CNO2(CH3)2CO + NO
Reaction order:   1
Temperature:   970 - 1200 K
Pressure:  4.56 - 5.57 bar
Rate expression:   9.1x1012 [s-1] e-167360 [J/mole]/RT
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Experimental procedure:   Shock tube
Excitation technique:   Thermal
Time resolution:   In both real time and by end product analysis
Analytical technique:   Other
Comments:   The products of the pyrolysis in shock-wave quenched samples were identified and quantitatively determined via GC, FTIR, GC/FTIR, and GC/MS. A compilation of 90 elementary steps was proposed. Numerical simulations based on this mechanism reproduce quantitatively the experimentally determined [NO2] vs time profiles for a range of conditions, as well as the distributions of major products
