固体超强酸是目前在石油化工、有机合成工业上的比较有前途的催化剂之一。其特点是催化活性较高,催化剂分离回收较易,反应过程中操作简便。固体超强酸的合成只是近十来年有较大进展,其中主要有 SiO_2—TiO_2,SiO_2—Al_2O_3等二元氧化物以及SbCl_5—SiO_2·TiO_2、FSO_3H—SiO_2·Al_2O_3等含卤素的固体超强酸,近来 SO_4~(2-)/M_xO_y型固体超强酸也有报导。我们以三种杂多酸为原料引入 SbCl_5,制备出未见文献报导的三种新型固体超强酸 Solid superacid is one of the more promising catalysts in the petrochemical and organic synthesis industries. It is characterized by high catalytic activity, catalyst separation and recovery easier, easy to operate during the reaction. The synthesis of solid superacid only made great progress in recent ten years, mainly including binary oxides such as SiO 2 -TiO 2 and SiO 2 -Al 2 O 3, halogen-containing solid superacids such as SbCl 5-SiO 2 TiO 2 and FSO 3 H-SiO 2 Al 2 O 3 SO_4 ~ (2 -) / M_xO_y type solid superacid has also been reported. We introduced three kinds of heteropoly acid as raw materials SbCl_5, prepared three new reports of solid superacid
