| Zusammenfassung: | A process for preparing N-formyl morpholine features the dewatering reaction of morpholine on formic acid at 50-200 deg.C under the existance of acidic catalyst and dewatering agent. The said catalyst is one or more of sulfuric acid, hydrochloric acid, phosphoric acid, zirconium sulfate, etc. The said dewatering agent is one or more of cyclohexane, benzene, toluene, xylene, etc. Its output rate can reach 99%. |
