Title:   Measurement and estimation of rate constants for the reactions of hydroxyl radical with several alkanes and cycloalkanes
Journal:   J. Phys. Chem. A
Volume:   110
Page(s):   3593 - 3604
Year:   2006
Reference type:   Journal article
Squib:   2006WIL/HAM3593-3604

Reaction:   iso-C4H10 + ·OH → Products
Reaction order:   2
Temperature:   229 - 403 K
Pressure:  1.01 bar
Rate expression:   3.18x10-12 [cm3/molecule s] (T/298 K)1.12 e-1013 [J/mole]/RT
Category:  Experiment
Data type:   Relative rate value measured
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Direct photolysis
Time resolution:   By end product analysis
Analytical technique:   GC-MS
Comments:   OH generated by 185-nm photolysis of H2O for most measurements above 0 C and by photolysis of N2O/H2 mixtures for low-temperature measurements. Good agreement reported in the overlap region, but above room temperature, rate constants from the N2O/H2 system were higher than for the H2O system, and were not used.
Rate constant measured relative to OH + n-butane (k = 1.68x10-11exp(-584/K) cm3s-1.
