The UV absorption measurements at 216 nm were carried out for three shock-heated mixtures, 1, 2, and 2 8% n-C4H10 diluted in Ar, in the temperature range of 1290–1610 K and at about half atmospheric pressures. From the initial absorption rise, which can be attributed to the CH3 growth, the rate constant of the reaction, n-C4H10=CH3+n-C3H7, was evaluated as k2=8.9×1013exp (−71.9 kcal⁄RT) (s−1). A computer modeling using a 44-reaction mechanism including the k2 value so evaluated could reproduce the absorption early in the reaction and in the temperature range of 1420–1610 K with a reasonable value.
在温度范围为1290-1610 K,且大约为半大气压的条件下,对三种冲击加热混合物(1、2和2 8%正丁烷稀释于氩气中)进行了216 nm的紫外吸收测量。根据初始吸收上升,可以归因于CH3的增长,反应n-C4H10=CH3+n-C3H7的速率常数被评估为k2=8.9×1013exp (−71.9 kcal/RT) (s−1)。使用包括评估出的k2值的44反应机理进行的计算机模拟,能够合理地再现反应早期的吸收情况和在1420-1610 K温度范围内的吸收情况。
