The thermal behavior of silver behenate has been studied by infrared spectroscopy, X-ray diffraction, combined thermogravimetry-differential thermal analysis-mass spectrometry. The results indicated that complicated phase transitions took place while heating silver behenate,but there were two distinct thermal transitions. During the first transition at 138°C, the alkyl chains of silver behenate were transformed from an ordered into disordered state.

通过采用粉末X射线衍射、红外光谱、热重-差热分析与质谱联用技术，对山嵛酸银纳米晶体的热行为研究发现，山嵛酸银受热发生了一系列相转变，它有两个明显的突变：即在138℃左右，山嵛酸银的烷基链从高度有序转变为无序状态；在231℃左右，山嵛酸银发生了热分解，其主要分解产物为银纳米粒子和山嵛酸。
