己内酰胺变温红外光谱研究
|
摘要
采用红外光谱(IR光谱)开展了己内酰胺的结构研究,采用变温红外光谱(TD-IR光谱)开展了温度变化对于己内酰胺结构的影响研究,并进一步研究了己内酰胺相变机理。。实验发现,随着测定温度的升高,己内酰胺的化学结构发生改变。本项研究拓展了TD-IR光谱在己内酰胺热变性的应用研究范围。
The caprolactam organic molecular structure was characterized by the infrared spectroscopy(IR spectrum). The temperature effect on caprolactam was studied by temperature-dependent infrared spectroscopy(TD-IR spectrum). The mechanism of phase transition of caprolactam was studied further. It is found that with the increase of temperature, the chemical structure of caprolactam changs. The study demonstrates the key roles of TD-IR spectrum in the analysis of thermal stability of the caprolactam.
