hydroxycarbonyl and hydroxynitrate products. Using a relative rate method, rate constants for reactions of the OH radical with n-decane, 3,4-diethylhexane and n-butylcyclohexane were measured and (in units of 10-12 cm3 molecule-1 s-1) were 12.5 ± 0.4, 7.43 ± 0.48 and 15.8 ± 0.6, respectively, where the errors do not include uncertainties in the rate constant for the n-octane reference compound. The products identified
已经在 296 ± 2 K 和大气压力下研究了 OH 自由基与 C10-烷烃正癸烷、3,4-二乙基己烷和正丁基环己烷的气相反应的动力学和产物。采用火焰离子化检测器气相色谱法 (GC-FID) 和气相色谱-质谱联用 (GC-MS) 鉴定和定量硝酸烷基酯和羰基产物,采用原位常压电离串联质谱法鉴定和定量,相对于内标、羟基羰基和羟基硝酸盐产品。使用相对速率法,测得 OH 自由基与正癸烷、3,4-二乙基己烷和正丁基环己烷反应的速率常数(以 10-12 cm3 分子-1 s-1 为单位)为 12.5 ± 0.4 ,分别为 7.43 ± 0.48 和 15.8 ± 0.6,其中误差不包括正辛烷参比化合物速率常数的不确定性。鉴定和量化的产品是:2-、3-、4-和 5-硝酸癸酯、羟基...
