| Abstract: | The surface of acid-activated palygorskite(denoted as Pa) was modified by grafting 3-aminopropyl-triethoxysilane(the silylated Pa,denoted as PaAPTES) for immobileizetion of molybdovanadophosphoric heteropoly acids(H5PMo10V2O40,denoted as PMoV).The samples were characterized by Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),and BET specific area measurement.The catalytic activity of the catalyst thus prepared was tested for the acetal of benzaldehyde with ethylene glycol.under the optim... |
