钨磷酸铵
3) ammonium phosphotungstate
磷钨酸铵
1.
Supported ammonium phosphotungstate catalyst was prepared by sol-gel method and characterized by X-ray diffraction(XRD) and IR spectra,and catalytic activity of catalyst in nitration of benzene was tested.
结果表明,负载催化剂保持了非负载磷钨酸铵杂多酸盐的Keggin结构;负载催化剂对苯硝化反应具有较高的催化活性,反应时间、催化剂用量以及硝酸与苯体积比对催化苯硝化反应有较大的影响,当反应温度为70℃时,最佳实验条件为:5mL苯、15mL硝酸、0。
