| 摘 要： | 采用气相色谱－付立叶变换红光谱对２－吡啶酮与１１种卤代烃加合物的结构进行了研究，并由ＧＣ／ＭＳ确证。结果表明，吡啶酮与卤代烃发生加合反应，在吡啶酮的环上氮位及环外氧位，生成两种互为同分异构体的加合物－氮位与氧位加物，所有氧位加合物在气相色谱中的保留时间比较氮加合物短。

| Abstract: | Abstract The adducts structure of 2 pyridone with eleven halohydeocarbons were characterized by GC/FTIR, and confirmed with GC/MS technique. The results showed that the adduction of 2 phridone with any halohydrocarbon produced two adduct isomers, at O site and N site, respectively. The retention time of all O adducts are shorter than that of N adducts in GC. The IR spectra are similar among the O adducts of different halohydrocarbons with 4 peaks between 1600 1280 cm-1 while the N adducts with a special a strong peak near 1690 cm-1 and two weak peaks at 1615 and 1540 cm-1 . The O and N adducts differ significantly. So the 2 pyridone adduct tautomers are easy to separate and identify by GC/FTIR. |
