Title:   A Kinetic Study of the Reaction of OH with Xylenes Using the Relative Rate/Discharge Flow/Mass Spectrometry Technique
Journal:   J. Phys. Chem. A
Volume:   113
Page(s):   12942 - 12951
Year:   2009
Reference type:   Journal article
Squib:   2009MEH/NGU12942-12951

Reaction:   1,4-Dimethylbenzene + ·OH → Products
Reaction order:   2
Reference reaction:   1,4-Dioxane + ·OH → Products
Temperature:   298 K
Pressure:  1.33E-3 - 1.33E-2 bar
Rate expression:   1.19x10-11 [±7.0x10-13 cm3/molecule s]
Category:  Experiment
Data type:   Relative value normalized by a reference value
Pressure dependence:   Rate constant is high pressure limit
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Discharge
Time resolution:   By end product analysis
Analytical technique:   Mass spectrometry
Comments:   The reaction exhibited prominent positive pressure dependence up to 5 Torr and reached a high-pressure limit at 8 Torr. The reported uncertainty is 2σ and includes contributions from scattering of the experimental data as well as from the uncertainty in the reference reaction rate constant.
