Abstract The crystalline lamellar compound, VOPO 4 ·2H 2 O, was employed as host to react with a long monoamine aliphatic chain, dodecylamine, and with an aromatic derivative, nicotinamide, using two distinct synthetic approaches: in the solid state and from aqueous solution. The resulting compounds were characterized by elemental analysis, infrared spectroscopy, X-ray diffractometry, thermogravimetry
摘要 结晶层状化合物 VOPO 4 ·2H 2 O 被用作主体,与长单胺脂肪链十二烷基胺和芳香衍生物烟酰胺反应,使用两种不同的合成方法:固态和水溶液. 通过元素分析、红外光谱、X 射线衍射、热重分析和 SEM 显微镜对所得化合物进行表征。根据 X 射线衍射图,计算出的含有十二胺的产物的层间距离增加了 2.05 nm,这与嵌入过程一致,并且在两种反应路线中均观察到。相反,客体烟酰胺分子没有插入到层状腔中。固态反应引起磷酸盐微观结构的微小改变,与求解过程相比较。通过与无机薄片形成 67° 角,脂肪胺分子在宿主腔内的双层中定向。两个系列合成化合物的热分解没有表现出任何行为差异。
