  Reactions of Hydrated Hydronium Ions and Hydrated Hydroxide Ions with Some Hydrocarbons and Oxygen-Bearing Organic Molecules

  摘要：

  The rate coefficients and ion products have been determined at 300 K for the reactions of H3O+.(H2O)(0,1,2,3) positive ions and OH-.(H2O)(0,1,2) negative ions with six hydrocarbons and six oxygen-containing organic species using a selected ion flow tube (SIFT) for the positive ions and a flowing afterglow (FA) for the negative ions. This study was initiated in support of a major development program of the SIFT and FA as chemical ionization devices for the analysis of trace gases in air and especially of human breath and the vapors emitted by fruits and food products. The H3O+ and OH- ions mostly react with the molecules, MH, via proton transfer, producing respectively MH(2)(+) and M(-) ions, which is ideal for gas analysis. The hydrated hydronium ions and the hydrated hydroxide ions are largely unreactive with the hydrocarbons included in this study, but they are very reactive with the oxygen-containing organic molecules undergoing ligand switching reactions producing mostly MH(2)(+) and M(-) hydrates. The details of the reactions (e.g. the number of H2O molecules either ejected from the intermediate complexes or remaining associated with the MH(2)(+) and MH(-) ''core ions'') are controlled largely by the reaction energy as far as this can be determined. The utility of the reactions of these hydrated ions as chemical ionization agents in atmospheric trace gas analysis is alluded to. Additionally,new FA data on the three-body association reactions of OH- and OH-. H2O with CO2 are presented.

  Alkyl cation transfer reactions between ethanol and protonated ethanol and ethanol and protonated propionitrile, as well as between n-propanol and protonated n-propanol have been investigated experimentally by low-pressure Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. The two ethyl cation transfer reactions were found to be the dominant reaction channels with association being

  已经通过低压傅里叶变换离子回旋共振（FT-ICR）质谱法实验研究了乙醇与质子化乙醇和乙醇与质子化丙腈之间以及正丙醇和质子化正丙醇之间的烷基阳离子转移反应。发现两个乙基阳离子转移反应是主要的反应通道，而缔合只是次要的反应途径。发现正丙基阳离子转移反应与缔合途径竞争，产生约 50:50 的质子化二正丙基醚和正丙醇的质子结合二聚体的混合物，具体取决于温度和压力。对于乙醇/质子化乙醇、乙醇/质子化丙腈，活化焓确定为 -16.1 ± 0.8、-17.5 ± 0.8 和 -15.7 ± 0.9 kJ mol-1，和正丙醇/质子化正丙醇烷基阳离子转移反应，分别。发现激活的熵基本相同，-121 ± 28 J K-1 m...
