摘要：

The CN + CH2CO and NCO + CH2CO reactions were studied over the temperature ranges 296-567 K and 296-556 K, respectively, using time-resolved infrared diode laser absorption and visible laser-induced fluorescence spectroscopy. The total rate constant data were fit to the following expressions: k(1)(CN + CH2CO) = (2.37 +/- 0.5) X 10(-11) exp[552.6 +/- 97/T] and k(2)(NCO + CH2CO) = (1.71 +/- 0.27) X 10(-12) exp[713.2 +/- 56/T] cm(3) molecule(-1) s(-1). Detection and quantification of CO product yields suggests that an addition-elimination mechanism producing CH2CN + CO or CH2NCO + CO dominates these reactions, and that hydrogen abstraction to produce HCN + HCCO or HNCO + HCCO is a minor or negligible product channel.
