摘要：

In this study, a magnetic recyclable Fe3O4@MCM-48-NaHSO4 nano catalyst was used for the synthesis of aminonaphtols with heteroaromatic amines and beta-amino carbonyls during the Mannich reaction. For this purpose, magnetite nanoparticles (MNPs) and MCM-48 mesoporous-coated MNPs with a particle size lower than 11 nm were synthesized via chemical precipitation methods. Then NaHSO4 was adsorbed on the surface of mesoporous MNPs. The prepared inorganic magnetic catalyst was characterized by FT-IR, XRD, UV-DRS, TEM, VSM and titration. Finally, the applicability of the synthesized solid acid catalyst for the catalysis of Mannich reactions was investigated.
