Title: Mesoporous SiO2-Al2O3: An Efficient Catalyst for Synthesis of 4,5-dihydro-1,3,5-triphenyl-1H-pyrazole
Abstract: Mesoporous SiO2-Al2O3 nano sized mixed metal oxide (MMO’s) used as a catalyst readily synthesized by hydrothermal method in high pressure autoclave. It shows highly efficient, recyclable and mild catalyst for the condensation reaction of substituted chalcone and phenyl hydrazine hydrate to obtain 4,5-dihydro-1,3,5-triphenyl-1H-pyrazole derivatives in excellent yields of product at short reaction times under simple experimental condition. The synthesized material particle size was controlled by CTAB as structure directing agent and calculated by BET Surface area. The structural characteristic of catalyst is identified by XRD, SEM, EDS, TEM analysis. The acidic strength of catalyst was measured by Ammonia- Temperature Programmed Desorption (NH3-TPD).
