Synthesis of Benzimidazole Using Reusable Nanocatalyst Zirconia and Sulfated Zirconia

Benzimidazole derivatives have been synthesized by solid Nanocatalysts Zirconia and Sulfated Zirconia with Green reusablity method. Synthesis of benzimidazole was carried out by conventional as well as microwave method. Synthesis carried out by reacting o-phenylenediamine and few aldehydes in the presence of catalytic amount of Nanoparticles. Particles used were sized in between 53-100 nm. Nanoparticles and synthesized benzimidazole derivatives were characterized by DLS, powder XRD, SEM-EDX andMass, CHNS, FT-IR, NMR analysis respectively.
