Title:   Measurements of Acetone and Other Gas Phase Product Yields from the OH-Initiated Oxidation of Terpenes by Proton-Transfer-Reaction Mass Spectrometry (PTR-MS)
Journal:   Atmos. Environ.
Volume:   35
Page(s):   6181 - 6191
Year:   2001
Reference type:   Journal article
Squib:   2001WIS/JEN6181-6191

Reaction:   beta-pinene + ·OH → pinonaldehyde + Products + (CH3)2CO
Reaction order:   2
Temperature:   297 K
Pressure:  1.00 bar
Rate expression:   no rate data available
Bath gas:   N2
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Direct photolysis
Time resolution:   In both real time and by end product analysis
Analytical technique:   Mass spectrometry
Comments:   By means of a multistep reaction chain, this study found that OH +?eta?pinene produces acetone (13% +/- 2%) and pinonaldehyde (25% +/- 3%).
