More Information
Summary:The present invention discloses catalytic process of preparing amine through reducing nitro compound with hydrogen. The process adopts nitro compound as main material, inorganic palladium salt microcapsule as catalyst in the amount of 0.01-2 %, and n-hexane, tetrahydrofuran, benzene, toluene or alcohol as solvent, and has hydrogen as catalyst in 0.1-2.0 MPa introduced to react at 20-80 deg.c for 1-10 hr. The present invention has reuse of inorganic palladium salt microcapsule as catalyst, and possesses the advantages of no pollution, mild condition, high operation safety, easy separation of the catalyst for reuse, etc.
