浸渍法制备ＳＯ２－４／ＺｒＯ２、ＳＯ２－４／Ｆｅ２Ｏ３、ＳＯ２－４／ＴｉＯ２三种固体超强酸，用指示剂法分别测定其酸强度，研究了制备过程不同焙烧温度对酸强度的影响，讨论了形成超强酸的必要条件．
Three solid superacid SO2-4 / ZrO2, SO2-4 / Fe2O3 and SO2-4 / TiO2 were prepared by impregnation method. The acid strength of three solid superacid SO2-4 / TiO2 and SO2-4 / TiO2 were measured by the indicator method. The influence of different roasting temperature on the acid strength was studied. The necessary conditions for the formation of super acid.
