USING THE METAL ORGANIC FRAMEWORKS (CUOBA) AS A CATALYST FOR REACTION OF 2-ACETYL-1-NAPTHOL AND BENZYL ETHER

Abstract

This study aimed to synthesize the compound of copper and 4,4'-oxysbisbenzoic acid (CuOBA), analyze its physical and chemical properties and employ it as a heterogeneous catalyst for the C-O coupling reaction of 2-acetyl-1-napthol and benzyl ether. The metal-organic framework material CuOBA was synthesized using the solvothermal method. The physicochemical characteristics of CuOBA were determined by several different analytical techniques, including X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR). CuOBA was used as a heterogeneous catalyst for the coupling reaction of the C-O connection between 2-acetyl-1-napthol and benzyl ether in good yield considering the factors of time, temperature, the concentration of reactants, solvents, and the mass of the catalyst. The results revealed that CuOBA, a catalyst for organic reactions, gave a conversion of 75.57%. The CuOBA catalyst was possible to reuse numerous times in the coupling reaction of 2-acetyl-1-napthol and benzyl ether without noticeable deterioration in catalytic efficiency. The direct esterification to produce 2-acetyl-1-naphthyl benzoate assisted by the CuOBA catalysts has not been reported in the literature before.
