| 摘 要： | 以大孔PVC树脂为载体．负载Keggin型杂多酸H3SiW12O40经过处理后得到了一种新型的杂多酸催化剂。本文采用电化学分析法测定负载杂多酸催化剂的总酸量及强、中、弱三种不同强度酸位的酸量，用吡啶-红外光谱测定出Bronsted酸和Lewis酸的比例．从而得出催化剂中Bronsted酸和Lewis酸的酸量及不同酸位的酸类型。

| Abstract: | A new type of heteropoly acids catalyst was prepared by supporting keggin heteropoly acids H_3SiW_(12)O_(40) onto PVC resin. The acid contents and the different intensity of strong, medium and weak acid were characterized by electrochemistry analyzed, and the acid ratio of bronsted and Lewis were characterized by pyridine-IR spectra. The acid types and their contents in different acid sites of catalysts were known. |
