摘　　要：以N-甲基吡咯为起始原料,二甲基甲酰胺(DMF)、三氯氧磷作反应试剂在80℃左右获得目标化合物,经二氯乙烷萃取、蒸馏得N-甲基-2-吡咯醛,收率90％。用二氯乙烷代替乙醚作萃取剂,具有溶剂回收套用好、安全、成本低等优点。N - Methyl - 2 - pyrrolealdehyde is prepared at around 80℃ with N - methyl - pyrrole as starting raw material and phosphorus oxychloride and dimethyl formamide (DME) as reaction reagents. It is then extracted by dichloroethane and finally obtained by vaccum distillation with a yield of 90% . The experimental result shows that, the use of dichloroethane as extractant instead of ether has the advantages of safe operation, high rate of solvent recovery and lower production cost.
