Title:   Gas-Phase Chemistry of Atmospheric Cl Atoms: A PLP-RF Kinetic Study with a Series of Ketones
Journal:   Atmos. Environ.
Volume:   37
Page(s):   455 - 463
Year:   2003
Reference type:   Journal article
Squib:   2003ALB/NOT455-463

Reaction:   n-C3H7COC2H5 + ·Cl → Products
Reaction order:   2
Temperature:   298 K
Pressure:  2.67E-2 - 0.27 bar
Rate expression:   6.69x10-11 [±6.2x10-12 cm3/molecule s]
Bath gas:   He
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   Rate constant is pressure independent
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Laser induced fluorescence
Comments:   The pulsed laser photolysis-resonance fluorescence technique (PLP-RF) has been used to determine the absolute rate coefficients for the gas-phase reactions of Cl atoms with a series of ketones at room temperature (298 K).

The measured values were independent of pressure over the range 20?00 Torr. These rate coefficients were compared with previous studies carried out by different techniques, when data were available. Results and atmospheric implications are discussed and compared with the reactivity with OH radicals.
