| 摘 要： | 本文报道了光促进下脂肪酸甲酯合成的新方法，并对１９种甲酯化产物的质谱（ＭＳ）图进行了分析。通过对这些甲酯ＭＳ图的分析，对含两种γ－Ｈ脂肪酸甲酯的Ｍｃｌａｆｆｅｒｔｙ重排进入了深入的探讨，并对同一类型甲酯随碳链增长时重排的规律进行了讨论。 |
| 关 键 词： | 脂肪酸甲酯 质谱 Mclafferty重排 |

| Abstract: | A new method was introduced here to prepare methyl ester of aliphatic acid under irradiation of ultraviolet. Analysis was performed for the MS spectra of 19 products, by which Mclafferty rearrangements were discussed of methyl ester of aliphatic acid with two kinds of gamma-H in details. The regularity of Mclafferty rearrangement was established for the same kind of methyl ester with the increase of the carbon chain. |
| Keywords: | Methyl ester of aliphatic acid Mass spectra Mclafferty rearrangement |
