Abstract:Synthetic conditions of methyl ethyl ketazine from butanone,NH3 and hydrogen peroxide was studied in the presence of catalyst. The optimal conditions was investigated through comparison of catalyst species, catalyst amount,hydrogen peroxide amount,reaction time and temperature. The yield of methyl ethyl ketazine reached 83.49% when formamide was used as the catalyst, quantity of catalyst and hydrogen peroxide both 0.5mol,reaction time 6 h,and reaction temperature 60℃. |
Key words:methyl ethyl ketazine;butanone;hydrogen peroxide;formamide;hydrazine hydrate |
