摘要
通过对传统制备方法的改进，用来自不同国家的原土，成功地合成了一种高耐热稳定性的铝支撑蒙脱土．用ＸＲＤ、化学分析、脱吸附分析、ＦＴＩＲ等手段表征了样品．结果表明：这种锅支撑蒙脱土在８００℃下可耐热４ｈ，并有高的比表面积及Ｌ和Ｂ固体酸．
he high thermal stability Al-pillared montmorillonites were successfully synthesized from the Chinese and American montmorillonitesby improved pillaring technique. The Al-pillared montmorillonites havebeen characterized by XRD, chemical analysis, adsorption-desorptionmeasurement and FTIR. The unusual thermal stability, high BET surface area, Bronsted and Lewis acidity for the Al-pillared montmorillonites have been observed after calcination at 800oC for 4 h.
