Title:   Formation of dimethylketene and methacrolein by reaction of the CH radical with acetone
Journal:   Phys. Chem. Chem. Phys.
Volume:   15
Page(s):   4049 - 4058
Year:   2013
Reference type:   Journal article
Squib:   2013GOU/DER4049-4058

Reaction:   CH3CHO + ·CHCH2=CHCHO +
Reaction order:   2
Reference reaction:   CH3CHO + ·CH → Products
Reference reaction order:   2
Temperature:   298 K
Pressure:  5.33E-3 bar
Rate expression:   6.1x10-1±1.2x10-1
Category:  Experiment
Data type:   Relative rate value measured
Pressure dependence:   None reported
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 methylketene photoionization spectrum measured in this work was used to reanalyze the results of an earlier study of the CH + acetaldehyde reaction. The estimated error is 20% of the branching ratio based on the uncertainty in the absolute photoionization cross-section of methylketene.
