Author(s):   Oehlschlaeger, M.A.; Davidson, D.F.; Hanson, R.K.
Title:   High-temperature thermal decomposition of isobutane and n-butane behind shock waves
Journal:   J. Phys. Chem. A
Volume:   108
Page(s):   4247 - 4253
Year:   2004
Reference type:   Journal article
Squib:   2004OEH/DAV4247-4253

Reaction:   iso-C4H102-C3H7 + ·CH3
Reaction order:   1
Temperature:   1310 - 1551 K
Pressure:  0.21 - 8.96 bar
Rate expression:   no rate data available
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Experimental procedure:   Shock tube
Excitation technique:   Thermal
Time resolution:   In real time
Analytical technique:   Vis-UV absorption
Comments:   Decomposition rates were determined by experimentally monitoring concentrations of CH3 resulting from isobutane decomposition and kinetic modeling of the experimental results. Reaction is in the falloff and displays complex pressure and temperature dependence, thus no single Arrhenius expression is given.
