Title:   Reactions of Methyl Radicals with Isobutane at Temperatures Between 800 and 950 Kelvin
Journal:   Int. J. Chem. Kinet.
Volume:   33
Page(s):   732 - 740
Year:   2001
Reference type:   Journal article
Squib:   2001GOO/HIP732-740

Reaction:   iso-C4H10 + ·CH3CH4 + tert-C4H9
Reaction order:   2
Temperature:   800 - 950 K
Pressure:  8.00E-2 - 0.13 bar
Rate expression:   2.17x10-15 [cm3/molecule s] (T/298 K)3.46 e-19200 [J/mole]/RT
Category:  Uncategorized
Data type:   Derived from fitting to a complex mechanism
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Thermal
Time resolution:   By end product analysis
Analytical technique:   Gas chromatography
Comments:   Heating of the reaction mixtures are achived through CO2-laser induced excitation of SF6 and V-T energy transfer to reactants.Methyl radicals are produced from thermal decomposition of di-tert-butyl-peroxide.Products are analyzed using GC/MS. Note: iso-butyl product corrected to tert-butyl (Aug 30, 2011)
