采用原位高温X射线衍射、原位红外光谱和热重-质谱联用技术,研究了共沉淀法制备的有机-无机纳米杂化材料[Mg0.68Al0.32(OH)2](C9 H13 NO 3S)0.130(CO 3)0.030·0.53H2O的热演化过程。结果表明,当在140 ° C和230°C之间热处理captopril-LDH时,首次观察到涉及碳酸盐-LDH和重新取向的有序度较低的captopril-LDH的亚稳态准间层层状纳米杂化物。层间有机物的主要分解/燃烧发生在270 - 550°C之间。提出了这种特定药物-无机纳米混合物在空气气氛中加热时化学和微观结构演变的示意性模型。
The thermal evolution of a crystalline organic–inorganic nanohybrid captopril intercalated Mg–Al layered double hydroxide (LDH) [Mg0.68Al0.32(OH)2] (C9H13NO3S)0.130(CO3)0.030·0.53H2O obtained by coprecipitation method is studied based upon in situ high-temperature X-ray diffraction, in situ infrared and thermogravimetric analysis coupled with mass spectroscopy analysis. The results reveal that a metastable quasi-interstratified layered nanohybrid involving carbonate-LDH and reoriented less ordered captopril-LDH was firstly observed as captopril-LDH heat-treated between 140 and 230°C. The major decomposition/combustion of interlayer organics occur between 270 and 550°C. A schematic model on chemical and microstructural evolution of this particular drug-inorganic nanohybrid upon heating in air atmosphere is proposed.
