Synthesis of β-Aminoketone Compositions by Mannich Three-Component with Nano Catalyst Fe3O4/SiO2/SA

Nano-catalysts are important in chemical processes, producing energy, saving energy and also preventing the environmental pollution(1). In this study, the effect of magnetic nano catalyst Fe3O4/SiO2/SA for the synthesis of β-aminoketone compositions by Mannich three-component reaction with acetophenone 1, aromatic aldehyde 2 and aromatic amines 3 have been studied.(2)The results showed that the reaction of β-amino-ketone and its derivatives functions better in the presence of the nano catalyst Fe3O4/SiO2/SA, and also the nano catalyst Fe3O4/SiO2/SA, in highest efficiency and the shortest possible time, leads to the production of the product, as well as the Fe3O4/SiO2/SA nano catalysts.(3)The purpose of this research is to replace the new acidic nano-catalysts rather than the other acid catalytic. In general, Fe3O4/SiO2/SA nano catalysts are one of the best catalysts for the reaction of β-amino ketone and its derivatives. The nano-magnetic catalyst was also characterized by BET surface area analyzer, FTIR and X-ray diffraction (SEM).
