چکیده

In the present project, Fe₃O₄ nanoparticles were prepared from the co-precipitation reaction of Fe^ц , Fe^ш in ammonia medium.  The obtained nanoparticles were used as a substrate to stabilize polyethylene glycol. To stabilize PEG on Fe₃O₄ surface, Fe₃O₄ hydroxy groups and PEG hydroxy group reacted in the presence of HCL. The resulting nanocomposite was structured by FT-IR spectroscopy and its morphology was examined by SEM.  Nanocomposite was used as an effective catalyst for four-component compaction between ammonium acetate, ethyl acetate, dimidone and aromatic aldehyde under solvent-free conditions. Polyhydroquinoline products were prepared in low times and with high efficiencies.
