Abstract
In the present study, for the first time, manganese ferrite nanoparticles with different Concentrations of manganese were placed in natural zeolite pores and the Zeolite/MnFe2O4 nanocatalysts were synthesized. Then, these nano catalysts have been applied in the synthesis of chalcone derivatives. First, the natural zeolite is activated under appropriate conditions. Then,manganese ferrite were synthesized by reaction of Fe2 (SO4) 3.H2O with MnCl2 and placed on the surface of activated nano zeolite. These modified zeolite catalysts have been thoroughly characteized by XRD, EDX, SEM, FT-IR, VSM and TEM analysis. The condensations of various aldehydes and acetophenone derivatives in the ratio of 1: 1 moll in the presence of a Zeolite/MnFe2O4 based nanocomposites under various solvents and solvent-free conditions were reported. Under optimized reaction conditions, various chalcone derivatives were synthesized and the products were obtained with good to excellent yields and high purities. Ambient reaction temperature, Short reaction times, easy work-up, reusability of the catalyst and no use of harmful
