【摘要】 本文用DTA和TG研究了羟基铝交联蒙脱土由室温至1000℃的脱水、脱羟基的过程以及脱水动力学。实验结果表明,与层柱状铝-蒙脱土相联系的有若干种不同类型的水分子和羟基,脱水过程遵循一级反应,而主要脱羟基过程始于570℃左右。更多还原

【Abstract】 Thermal dehydration,dehydroxylation and the kinetics of Al-montmorillonites were studied together with DTA and TG. The results show that there are many different types of water molecules and hy-droxyl groups attached to the Al-monlmorillonite flakes and the dehydration obeys the first order reaction. The main dehydroxylation process of all the samples start at about 570℃.更多还原
