四极质谱中的离子－分子缔合反应Ⅱ．芳香醛和酮及其相关化合物的四极质谱

Ion-Molecule Association Reactions in Quadrupole Mass Spectrometry Ⅱ. The Quadrupole Mass Spectrometry of Aromatic Aldehyeds, Ketones and Their Related Compounds

探讨了未取代和取代的芳香醇和酮、芳香二酮和安息香及其醚等在四极质谱中的特点和规律。结果表明，在芳环上无吸电子基团的情况下，芳香醛和酮均可发生离子－分子缔合反应，生成［Ｍ＋ＡｒＣＯ］＋和［Ｍ＋Ａｒ］＋等加合离子，羰基氧是此类反应中的供体原子。

The behavoirs of unsubstituted and substituted aromatic aldehydes, ketones andbetals, diketones, as well as benzoin and its ethers in quadrupole mass spectrometrywere explored. The results of experiments show that the ion--molecule association reactions taken place in the case of no electroabstracting group on the aromatic ring, andthen the adduct ions LM+ArCOJ+ and [M+ArJ+ formed. The carbonyl oxygen servesas donor atoms in this type of association reaction.
