氨化法合成3,5-二甲基苯胺的工艺研究

A Study on the synthesis of 3,5-dimethylaniline by Amination

在钯碳催化剂存在下,3,5-二甲基苯酚通过部分加氢再氨化,生成3,5-二甲基苯胺。3,5-二甲基苯酚的转化率为95％,3,5-二甲基苯胺的产率为52％。

3,5-Dimethylaniline was prepared by catalytic amination of 3,5-dimethylphenol in the presence of palladium on charcoal. The conversion of 3,5-dimethylphenol and the yield of 3,5-dimethylamine were 95% and 52% respectively.
