Complex solid acid of SO2-4 /SnO2-WO3/KIT-6 was prepared through impregnation method using KIT-6 as template. The solid acid was used as catalyst for the Baeyer-Villiger oxidation of cyclic ketones and the condensation reaction between ketones/aldehyde and diols. It was found that the synthesized solid acid exhibited promising catalytic activity in the two kinds of reactions. The introducing of the WO3 and KIT-6 increased not only the acidity but also the specific area of the solid acid, therefore, the catalytic activity of the solid acid was enhanced.%以KIT-6为模板剂，采用浸渍法合成了复合型多孔固体酸催化剂SO2-4/SnO2-WO3/KIT-6。用XRD、 BET、 TEM等手段对催化剂进行了表征，表明催化剂具有良好的介孔结构。将所得催化剂应用于催化环酮类化合物的Baeyer-Villiger氧化反应以及醛酮与二醇的缩合反应中。结果表明，所得固体酸在两类反应中都具有较好的催化性能。第二组份WO3和模板剂KIT-6的引入，有效地提高了催化剂的酸性和比表面积，促进了催化剂活性的提高。
