Özet:

 Heterogeneous Bronsted acid is one of the most promising compounds that can be used as a catalyst in chemical production, and that can certainly have a positive impact on the environment. This research includes the preparation of heterogeneous Bronsted acid by using rice hulls as a starting material. The prepared acid was characterized by FTIR, XRD, TGA, SEM-EDX, TEM, and elemental analysis. The FTIR results showed the presence of N-H and SO absorption bands within the expected range in prepared Bronsted acid. The specific surface area of the catalyst determined by Brunauer-Emmett-Teller BET using the nitrogen adsorption method is 205.42 m2g, and the average pore diameters are 3.69 nm, 2,4,5-Trisubstituted imidazole derivatives were prepared by reacting substituted aldehydes with benzil and ammonium acetate in the presence of a solid acid catalyst. The main advantages of this method are safe, cheap, and short reaction conditions. In addition, the prepared catalyst can be reused.
