摘要
Oxidation Of cyclo-C5H5 was investigated by monitoring O atoms and also CO molecules behind the reflected shock of cyclo-C5H6/O-2/Ar and C6H5OCH3/O-2/Ar mixtures. In both mixtures we could observe the formation of O atoms produced by the reaction of cyclo-C5H5+O-2 --> cyclo-C5H5O + O and from the kinetic analysis of these time profiles the rate constant for this reaction was determined to be k = 8.5 x 10(14) exp(-117.0 kJ/RT) cm(3)mol(-1)s(-1). The possibility of CO formation by the reaction of cyclo-C5H5O --> C4H5+CO was also investigated but because of the subsequent reactions forming CO molecules no direct information for the reaction of cyclo-C5H5O --> C4H5+CO was derived.
