preparation and characterization of pvc/nife2o4/fe2o3 composite: catalytic activity for synthesis of arylidene barbituric acid derivatives

Pvc/nife2o4/fe2o3 composite was successfully synthesized and characterized by fourier transform infrared spectroscopy (ft-ir), x-ray powder diffraction (xrd), and scanning electron microscopy (sem). also, the catalytic activity of pvc/nife2o4/fe2o3 has been considered in the synthesis of two arylidene barbituric acid derivatives. the ft-ir and xrd results confirmed the synthesis of pvc/nife2o4/fe2o3 composite. according to scherre equation and the main peak at about 2θ = 41.72º, the average crystalline size of the nanoparticles determined at about 75 nm. catalytic activity results show that the as-prepared composite is as an efficient catalyst. this study suggests that other pvc composites could be explored as a new catalyst for synthesis of other arylidene barbituric acids.
