摘要
Na蒙托石的层间离子被各种金属离子交换取代后，经不同条件的热处理，表面酸性发生了变化．用CVL显色法评价其表面酸性，结果表明金属离子类型、浓度以及热处理温度等对表面酸性有不同程度的影响．以交换后的Ni蒙托石为一元酸酯化催化剂，具有较高的催化活性．
The acidic property of sodium montmorillonite changes after its interlayer ions being replaced by various metallic ion exchange and heat treated under different conditions. Its surface acidic property can be evalualed by CVL coloration method. As shown by the results, type and concentration of metallic ions and temperature of heat treatment exercise influence in different degrees. As a monobasic acid esterification catalyst, the cxchanged sodium montmorillonite shows a higher catalvtic activity.
