摘要
在研究已有的合成工艺的基础上,以吗啉和甲酸为原料,合成N甲酰吗啉,并考察了影响该反应过程的主要因素。选用了适宜的带水剂循环,确定了较佳工艺条件为吗啉∶甲酸=1∶0.97(摩尔比),反应温度90～100℃,反应时间8.5h。N甲酰吗啉的总收率为91.5%(以吗啉计)。
The article studied synthesizing technique for producing N-formylmorpholine by the reaction between morpholine and formic acid. Better water carrying agent was selected which controlled experiment temperature. The influence of main factors on reaction process were examined and the optimum technological conditions was obtained as followed: mole ratio of morpholine to formic acid is 1∶0.97, reaction temperature is 90～100℃ and reaction time is 8.5 h. The total recovery rate of N-formylmorpholine is 91.5% on the morpholine.
