| 摘 要： | 合成了Ｈ３ＰＭｏ１２、Ｈ４ＳｉＭｏ１２杂多酸的一系列铯盐：ＣｓｘＨ３－ｘＰＭｏ１２Ｏ４０·ｍＨ２Ｏ（ｘ＝０￣３，ｍ＝４￣７），ＣｓｘＨ４－ｘＳｉＭｏ１２Ｏ４０·ｍＨ２Ｏ（ｘ＝０￣４，ｍ＝４￣７）。测定了它们的酸强度、ｐＨ滴定曲线、ＮＨ３－ＴＰＤ、ＩＲ光谱和比表面积。以乙酸和正丁醇的酯化为探针反应，考察了催化剂的酸催化活性。实验结果表明，杂多酸铯盐对乙酸和正丁醇的催化酯化活性只与总酸量有关，与表面积

| Abstract: | A series of Cs+ salts of heteropo lyacids (HPMo12, HSiMo12) w ere synthesized Their acidity was studied and their specific surface areas were deteim fined by BET-method The acid catalytic activity of various saltswas also investigated using the esterification of HAc and n-butyl alcohol as a test reaction. The results showed that the acid contents are noton the surface but in the bulk responsible for the catalytic activity Itmeans that the reaction is carried out in the pseudo-liquid phase |
