摘　　要：用红外光谱和Ｘ射线光电子能谱对浸渍法制得的ＳＯ２－４／ＴｉＯ２和ＳＯ２－４／ＺｒＯ２催化剂进行了表征，以ＮＨ３的ＴＧ技术对其酸性进行了研究，并同丁烯与异丁烷的烷基化反应和苯甲酰氯与甲苯的酰化反应的催化活性关联．结果表明。Samples of SO 2- 4/TiO 2 and SO 2- 4/ZrO 2, prepared by impregnation method, were characterized using infrared(IR) and X ray photoelectron spectroscopy. The acidvity was determined by TG of NH 3. The experimental results were correlated with the catalytic activity for the alkylation of isobutane with butenes and the acetylation of benzoyl chloride with toluene. It was found that catalytic activity was corresponding relation with the acidity.
