Title:   Formation of HCNO and HCN in the 193 nm Photolysis of H2CCO in the Presence of NO
Journal:   Chem. Phys. Lett.
Volume:   356
Page(s):   181 - 187
Year:   2002
Reference type:   Journal article
Squib:   2002ESH/KOC181-187

Reaction:   NO + HCCOHCN + CO2
Reaction order:   2
Temperature:   298 K
Pressure:  3.50E-3 bar
Rate expression:   no rate data available
Category:  Experiment
Data type:   Mechanistic information only
Pressure dependence:   None reported
Experimental procedure:   Flow tube - Data taken vs distance
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   By end product analysis
Analytical technique:   Mass spectrometry
Comments:   The products obtained from the ArF laser photolysis of H2CCO in the presence of excess NO were investigated in a tubular flow reactor by time-resolved mass spectrometry. Photolysis of H2CCO produces both CH2 and HCCO, each of which may react with NO to produce HCN and HCNO. The overall branching ratio to HCNO was found to be (0.78 +/- 0.18) and that to HCN was (0.19 +/- 0.04). The authors were unable to separate the contributing channel information.
