Synthesis of the Magnetic Nanoferrites of Spinel Type and Use in Esterification Reaction for Biodiesel Obtaining

Abstract:

Nanotechnology has been important in improving of the properties of the materials used in the manufacture of magnetic devices, electromagnetic radiation absorbers, cell telephony, pigments and lately in catalysis in transesterification and esterification reactions to biodiesel obtaining. The objective of this work was to synthesize and characterize magnetic materials of spinel type compound of CuFe₂O₄, CoFe₂O₄, MnFe₂O₄, NiFe₂O₄ and FeFe₂O₄ and to check the catalytic effect on the methyl esterification reaction of soybean oil. The samples were obtained by combustion reaction and characterized by XRD, FTIR, BET and SEM. The results analysis revealed for nanoferrites the spinel phase formation and higher specific area to the sample CoFe₂O₄. Generally the samples presented in irregular agglomerates form. All samples were catalytically active in the esterification reaction, with the highest conversion obtained by the sample MnFe₂O₄ with 57%.
