    使用离子迁移谱测量质子亲和性
    摘要:
    摘要 相对质子亲和力通常通过高压质谱法测量。在这项工作中,离子迁移谱用于确定质子亲和力。发现MH++N⇌M+NH+反应的标准摩尔焓变ΔH0M为: -(56.3±0.8) kJ · mol -1 ,当M为乙酸乙酯和N乙醇时;-(27.8±0.5) kJ · mol -1 ,当M为苯乙酮和N乙酸乙酯时;-(10.6±0.2) kJ · mol -1 ,当M为环庚酮和N乙酸乙酯时;-(66.1±1.2) kJ·mol -1 ,当M为甲基膦酸二甲酯和N乙酸乙酯时;并且,-(56.7±0.9) kJ · mol -1 ,当M是甲基膦酸二甲酯和N环庚酮时。这些值在内部是一致的,并且与高压质谱法获得的结果非常一致。基于环庚酮和乙酸乙酯的质子亲和力,

  • Gas-phase protonation and methyl cation transfer from methyl halide ions
    作者:R. Houriet、E. Rolli、R. Flammang、A. Maquestiau、G. Bouchoux

    AbstractThe ion‐molecule reactions between [CH3X]+˙ [CH3XH] +, [CH3XCH3]+ ions (X = F, Cl, Br, I) and a number of nucleophiles have been studied by ion cyclotron resonance techniques. Protonation of the nucleophiles is observed to occur from both the molecular ions [CH3]X+˙ and protonated species [CH3XH]+ whereas dimethylhalonium ions [CH3XCH3]+ react principally by methyl cation transfer. A notable exception occurs in methyl iodide where the molecular ions [CH3I]+˙ act both as proton and methyl cation donors, whereas dimethyliodonium ions are found unreactive. The results are discussed with reference to the use of alkyl halides as reagent gases in chemical ionization experiments.
  • Proton affinity measurements using ion mobility spectrometry

    Abstract Relative proton affinities are usually measured by means of high pressure mass spectrometry. In this work ion mobility spectrometry was used to determine proton affinities. The standard molar enthalpy change ΔH0M for the reaction MH++N⇌M+NH+ was found to be: −(56.3±0.8) kJ · mol −1 , when M was ethyl acetate and N ethanol; −(27.8±0.5) kJ · mol −1 , when M was acetophenone and N ethyl acetate;
