The recombination of c-C5H5 with H-atoms has been studied behind reflected shock waves. The obtained rate coefficients are almost independent of temperature and were found to be krec = 2.6 × 1014 cm3 mol−1 s−1 for pressures around 2 bar in the temperature range between 1150 and 1500 K. Together with rate coefficients for the dissociation, obtained in an earlier work (Roy et al., Proc Combust Inst 1998
已经在反射冲击波后面研究了 c-
C5H5 与 H 原子的复合。得到的速率系数几乎与温度无关,在 1150 到 1500 K 的温度范围内,压力约为 2 bar 时,krec = 2.6 × 1014 cm3 mol-1 s-1。连同解离的速率系数,得到在较早的工作(Roy 等人,Proc Combust Inst 1998, 27, 329–336)中,在接近当前工作中应用的压力和温度下,我们计算了
C5H6 ⇌ c- + H 的平衡常数 Kc(T) . 进行了“第三定律”分析。分别得出
环戊二烯基 DHf,0 = 65.4 ± 1 kcal mol-1 和 DHf,298 = 62.5 ± 1 kcal mol-1 的形成焓数据。该分析基于最近由 Kiefer 等人计算的
环戊二烯基熵的新结果。(J phy chem,出版中)。最后,我们的测量数据进行了衰减分析。模拟结果非常令人满意。©
