Author(s):   Curran, H.J.
Title:   Rate constant estimation for C-1 to C-4 alkyl and alkoxyl radical decomposition
Journal:   Int. J. Chem. Kinet.
Volume:   38
Page(s):   250 - 275
Year:   2006
Reference type:   Journal article
Squib:   2006CUR250-275

Reaction:   i-C3H7O(CH3)2CO +
Reaction order:   1
Temperature:   298 - 2000 K
Rate expression:   5.62x1013 [s-1] (T/298 K)-0.48 e-84015 [J/mole]/RT
Category:  Review
Data type:   Extensive literature review
Pressure dependence:   Rate constant is high pressure limit
Comments:   Rate coeficients for alkyl and alkoxy radical decomposition reactions, as well as the corresponding reverse adddition reactions, are recommended on the basis of review of large volume of literature and correlations between activation energies and reaction types. The temperature range of recommendations is uncertain. The range cited here (298 - 2000 K) is based on the largest temperature interval used by the author in an Arrhenius plot.
