研究了肉豆蔻酸交换的锂铝层状双金属氢氧化物的热学和光谱性质。在厌氧环境中，层状结构在高达250摄氏度时是稳定的。差热分析表明，在此温度范围内，存在部分脱羟基的金属层。这导致材料具有相当高的表面积。热处理后的肉豆蔻酸链呈现无序状态，其在冷却样品时保留。高孔隙率和疏水性使该材料成为气相色谱中固定相的候选者。参考文献21篇，图7。
The thermal and spectroscopic properties of myristic acid-exchanged lithium aluminum layered double metal hydroxide are examined. In an anaerobic environment, the layered structure is stable up to 250{degrees}C. Differential thermal analysis indicates that in this temperature range there is partial dehydroxylation of the metal layer. This results in a material of considerably higher surface area. The myristic acid chains after heat treatment assume a disordered state, which is retained upon cooling the sample. The high porosity and the hydrophobicity make this material a candidate for a stationary phase in gas chromatography. 21 refs., 7 figs.
