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