Synthesis of Cobalt Doped ZnAl2O4 Nanoparticles in the Presence of Citric Acid Prepared by Co-precipitation Method as a New Heterogeneous Catalyst for the acetylation of Bisphenol A

Cobalt doped zinc aluminate nanoparticles easily prepared by the co-precipitation method using aqueous Thisnanosized spinel-type oxide was characterized by TGA, XRD, FT-IR, TEM, and surface area measurement and used asthe heterogeneous catalyst for the acetylation reaction. Efficient acetylation of bisphenol A, carried out overCo0.5Zn0.5Al2O4 nanoparticles using acetic anhydride the acetylating agents at room temperature The method is highlyselective and sensitive method. This method is fast and has a high yield. It is also clean, safe, cost effective, compatiblewith substrates that have other functional groups and very suitable for practical organic synthesis. In addition, the catalystcan be reused without significant loss of activity. Indeed, the catalytic activity of the Co0.5Zn0.5Al2O4 nanoparticles ishigher than that of bulk Co0.5Zn0.5Al2O4.
