摘要
Abstract
To break the traditional synthesis limitations such as low percent conversion, over commission of peroxide and so on, this paper synthesizes 3-methylpyridine-N-oxide from 3-methypridine using H2O2 as oxi-dant, homemade catalyst as catalyst. By researching the influence of different catalysts, catalyst dosage, reac-tion time, material ratio, reaction temperature and other factors in the reaction, the results show that the new catalyst results were clear, when the optimal reaction conditions were 4.5 % of 3-methylpyridine, the fraction of molar ration of 3-methylpridine and H2O2 and acetic acid was 1∶1.5∶1.5~1∶1.6∶1.6, the temperature was 80℃, and the promising conversion of the reaction was over 98.1%.关键词
