✦ Synopsis

The kinetics of the reaction of CH2OH with O(3P) has been investigated in a heatable tubular reactor coupled to a photoionization mass spectrometer. The decay of CH2OH was monitored as a function of O-atom concentration (

tO determine rate constants as a function of temperature and pressure. The rate constants are independent of density and were fit to an Arrhenius expression: (1.09_+0.37) X 10 -t° exp[ (2.9_+ 0.9) kJ mol-I/RT] cm 3 molecule -t s -~ over the temperature range 300-508 IC Both formaldehyde and formic acid were detected as products of the CH2OH + O (3P) reaction.
