• Chemical kinetics and thermodynamics of tin ionization in H₂-O₂-N₂ flames and the proton affinity of SnO
  作者：John M Goodings、QingFeng Chen

  DOI：10.1139/v98-172

  日期：1998.10.1

  A small amount (<10^-6 mol fraction) of tin was introduced into five, fuel-rich, H₂-O₂-N₂ flames in the temperature range 1820-2400 K at atmospheric pressure. Ions in a flame were observed by sampling the flame along its axis through a nozzle into a mass spectrometer. The major neutral tin species in these flames were SnO (>97%) and Sn (<3%). The principal tin ions observed were SnOH⁺ and Sn⁺. Thermodynamic functions for SnOH⁺, Sn⁺, SnO, and Sn were calculated by statistical mechanics using published data from ab initio calculations and spectroscopy. The SnOH⁺ ion was formed initially by proton transfer to SnO by H₃O⁺, a natural flame ion, with which it is in equilibrium. It was also produced by chemi-ionization of SnO reacting with H; SnOH⁺ rapidly equilibrates with Sn⁺. Ion ratio measurements of SnOH⁺/H₃O⁺ led to the proton affinity PA°₂₉₈ (SnO) = 911 ± 21 kJ mol ^-1 (218 ± 5 kcal mol^-1). A calculated equilibrium constant provided the SnOH⁺/Sn⁺ ion ratio. When electron-ion recombination of SnOH⁺ with free electrons was made dominant by the addition of CH₄ and K, the measured recombination coefficient of SnOH⁺ was (0.116 ± 0.065)T^{-(1.66±0.16)} cm³ molecule^-1 s^-1; the temperature dependence is in good agreement with the T^-1.5 dependence predicted by simple theory. The rate constant for chemi-ionization could not be measured due to impurity ions from potassium and sodium, but the equilibrium constant for chemi-ionization/recombination was calculated to be 0.004 863 exp (-52 070/T). Assuming detailed balance and the experimental recombination coefficient, the relatively small rate constant for chemi-ionization was given by 3.27 × 10^-10 exp (-48 630/T) cm³ molecule^-1 s^-1. Finally, calculated values were obtained for the bond energy D°₀(HO-Sn⁺) = 408 ± 21 kJ mol^-1, and the standard zero-point enthalpy of formation delta_fH°₀(SnOH⁺) = 637 ± 21 kJ mol^-1.Key words: flame ionization, chemi-ionization, proton affinity, mass spectrometry, tin.

  在大气压下，将少量锡（<10^-6摩尔分数）引入了五个富含燃料的H2-O2-N2火焰中，温度范围为1820-2400K。通过将火焰沿着喷嘴轴线取样进入质谱仪来观察火焰中的离子。这些火焰中的主要中性锡物种是SnO（>97%）和Sn（<3%）。观察到的主要锡离子是SnOH+和Sn+。使用从从第一性原理计算和光谱学中发表的数据，通过统计力学计算了SnOH+、Sn+、SnO和Sn的热力学函数。 SnOH+离子最初通过自然火焰离子H3O+与其处于平衡的SnO之间的质子转移形成。它也是通过SnO与H反应的化学电离产生的，SnOH+与Sn+迅速达到平衡。SnOH+/ +的离子比测量导致质子亲和力PA°298（SnO）= 911±21 kJ mol^-1（218±5 kcal mol^-1）。计算的平衡常数提供了SnOH+/Sn+离子比。通过添加CH4和K使电子-离子复合反应成为主导，测得SnOH+的复合系数为（0.116±0.065）T^（-（1.66±0.16））cm^3 molecule^-1 s^-1；温度依赖性与简单理论预测的T^-1.5依赖性符合得很好。由于钾和钠的杂质离子，无法测量化学电离的速率常数，但计算出了化学电离/复合反应的平衡常数为0.004863exp（-52070/T）。假设详细平衡和实验复合系数，化学电离的相对较小的速率常数为3.27×10^-10exp（-48630/T）cm^3 molecule^-1 s^-1。最后，计算得到键能D°0（HO-Sn+）=408±21 kJ mol^-1，标准零点生成焓deltafH°0（SnOH+）=637±21 kJ mol^-1。关键词：火焰电离，化学电离，质谱法，质子亲和力，锡。
