Abstract :A multifunctional heterogeneous acid catalyst named as spFe3O4@SBA-15@HPW was prepared, which consists of versatile properties such as magnetic separability, high conversion efficiency and reusability. This catalyst was characterized by XRD, FT-IR, VSM, TEM and SEM/EDX techniques with respect to structural, morphological and magnetic properties. The catalyst showed higher catalytic activity than the commercial catalysts such as Amberlyst-15 and Dowex 50Wx4 and also heteropoly tungstic acid insert ignore into journalissuearticles values(HPW); alone in terms of conversion of oleic acid for biodiesel production by the esterification of oleic acid with methanol. The experimental data were correlated by pseudo-first-order homogeneous and Eley-Rideal heterogeneous models, and the results demonstrate the suitability of Eley-Rideal mechanism.
