【Abstract】 The synthesis of N formylmorpholine was studied. Morpholine is the main raw material, and formic acid or methyl methanoate is aclyting agent. In the presence of catalyst, morpholine was reacted under thermory and pressure. The result of experiment show that at the presence of catalyst the conversion of morpholine reaches 95%, and purity of distilled N formylmorpholine reaches 99%.更多还原
