Recent molecular simulation findings with several kaolinite intercalate complexes raised the question of the existence of more than one stable state, which has not been confirmed by experimental observations yet. Kaolinite/potassium acetate intercalate complexes were synthesized and examined by X-ray diffraction, and a molecular simulation study was performed for the system. Consistent with the suggestion from the simulations, an additional stable basal spacing was found experimentally at d(001)=1.168nm besides the well-known one at d(001)=1.403nm.
最近,几种高岭石插层复合物的分子模拟研究结果提出了是否存在不止一种稳定状态的问题,但尚未得到实验观察的证实。我们合成并通过 X 射线衍射研究了高岭石/乙酸钾插层复合物系统,并进行了分子模拟研究。与模拟结果的建议一致,实验中除了众所周知的 1.403nm 间距外,还发现了另一个稳定的基面间距 d(001)=1.168nm。
