焙烧温度对二氧化硅负载磷钼酸铵催化剂苯硝化活性的影响
Effect of the Calcination Temperature on the Catalytic Activity of Silica Supported Ammonium Molybdophosphat Catalyst for Benzene Nitration
摘要
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.关键词
