| Abstract: | After drying and calcination,silica supported ammonium molybdophosphat catalyst was prepared by sol-gel method with ethyl orthosilicate as silica source.And the catalyst was characterized by X-ray diffraction(XRD),IR spectra and the potentiometric titration method,as well as the catalytic activity of catalyst in nitration of benzene was tested.Results indicated that calcination temperature had obvious influence on the catalytic reaction,and the catalyst that calcinated at 300℃ exhibited excellent catalytic activity and stability. |
