| 摘 要： | 利用酸碱滴定的方法，考察了浸渍时间、SiWl2杂多酸溶液浓度和不同溶剂对杂多酸负载量的影响。结果表明，以粗孔硅胶为载体时，浸渍6h，硅钨杂多酸浓度为60mg／ml时的负载量最大，此时粗孔硅胶孔径大小对溶剂化的SiWl2酸分子的扩散起主要作用。

| Abstract: | The effect of time concentration and solvent on 12 sillcotungstic acid load was investgated by the method of acid base titration.It shows that the SiW 12 /SiO 2 catalyst possesses high loading level of SiW 12 after the macroporous silica was impregrated with 60 mg/ml aqueous SiW 12 solution for 6 h,and the pore diameter of the silica gel is mainly responsible for the diffusion of the solvented SiW 12 . |
