| 摘 要： | 利用X射线粉末衍射和Fourier变换红外光谱实验分析了2种高岭石及其苯甲酰胺插层复合物的结构.结构表征与分析表明:复合物的层间距分别扩张到1.437 nm和1.444 nm,苯甲酰胺分子在高岭石层间均呈单分子竖直排列,但与层间表面的倾斜状况不同.在佛山高岭石/苯甲酰胺插层复合物中,氨基和羰基同时参于与内表面羟基的作用;而在苏州高岭石/苯甲酰胺插层复合物中,只有氨基与内表面羟基成键,且苯甲酰胺分子还部分嵌入高岭石的复三方空穴.

| Abstract: | The structures of the two types of kaolinite and their benzamide intercalation compounds were characterized by the powder X-ray diffraction and Fourier-transformed infrared spectroscopy. The results show the basal spacing of the kaolinite-benzamide intercalation compotmd expands to 1.437 nm and 1.444 nm respectively, and the benzamide molecules both adopt a perpendicular stance between the layers of kaolinite, but the states of the intercalation are different. The inner-surface hydroxyls of the kaolinite form hydrogen bonds with both the amino groups and carbonyl groups in the Foshan kaolinite-benzamide intercalation compound, but the amino groups in the Suzhou compound form sufficient bonds, with the benzamide moleculaes partly are embedded into the ditrigonal hole of kaolinite. |
