Author(s):   Park, J.; Gheyas, S.I.; Lin, M.C.
Title:   Kinetics of C6H5 Radical Reactions with 2-Methylpropane, 2,3-Dimethylbutane and 2,3,4-Trimethylpentane
Journal:   Int J. Chem. Kinet.
Volume:   31
Page(s):   645 - 653
Year:   1999
Reference type:   Journal article
Squib:   1999PAR/GHE645-653

Reaction:   iso-C4H10 + PhenylBenzene + tert-C4H9
Reaction order:   2
Temperature:   295 - 972 K
Pressure:  4.00E-3 - 5.33E-2 bar
Rate expression:   4.65x10-13 [±2.49x10-13 cm3/molecule s] e-12571 [±366 J/mole]/RT
Category:  Experiment
Data type:   Absolute value measured directly
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Mass spectrometry
Comments:   The rate constant is higher than the only measurement by 1962DUN/TRO4672. However, the previous rate constant is obtained from the assumed C6H5 recombination rate, and the study was carried out at unspecified wavelengths.
