Title:   Spectrokinetic Study of the Reaction System of 2NO 2<-> N2O4 with Butanols Between 320-358 K in the Gas Phase
Journal:   Pol. J. Chem.
Volume:   83
Page(s):   131 - 143
Year:   2009
Reference type:   Journal article
Squib:   2009WOJ/JOD131-143

Reaction:   (CH3)2CHCH2ONO + HNO3iso-C4H9OH + N2O4
Reaction order:   2
Temperature:   320 - 358 K
Pressure:  0.25 - 0.50 bar
Rate expression:   4.66x10-17 [cm3/molecule s] e-23200 [±4300 J/mole]/RT
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Pressure dependence:   Rate constant is pressure independent
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Thermal
Time resolution:   In real time
Analytical technique:   Vis-UV absorption
Comments:   Reaction was studied in the 320 - 358 K temperature range. The activation energy and the value of the rate constanst extrapolated to 298 K were reported by the authors; the preexponential factor was not reported. The value given here is calculated from the reported k(298K) and the activation energy.
