摘要
制备了水滑石 Mg6Al2 (OH) 16CO3 · 4 H2 O和 Mg4 Al2 (OH) 12 (NO3 ) 2 · 4 H2 O,它们的晶体结构基本相似 ,2 0 0～ 4 0 0℃时将失去全部层间阴离子。其表面带有碱性活性中心 ,可以作酯交换反应的催化剂 ,使用该催化剂反应产率达 98.
Hydrotalcites have been prepared and characterized. Their crystalline structure are resemble. When the temprature reached 200～450 ℃, it will lose all its anions situated in the interlayer space. Because its surface alkali active centres, it can be used as esterinterchange reaction catalyst. The yield was over 98.5%.
