外消旋新黄皮酰胺酮的热稳定性研究

Thermostability of racemic neoclausenamidone

用差示扫描量热法(DSC)和热重分析(TG)两种热分析方法研究外消旋新黄皮酰胺酮的热稳定性及热分解过程。在氮气氛(氮气流量为20mL/min)、10K·min-1的升温条件下,外消旋新黄皮酰胺酮固体在232~335℃之间发生激烈的分解反应,至475℃时分解完全。

The thermal decomposition of racemic neoclausenamidone was studied using differential scanning calorimetry and thermogravimetry. Neoclausenamidone decomposed rapidly between 232 ℃ and 335 ℃ in the nitrogen stream with a heating rate of 10 K·min^(-1). Complete decomposition happened at the temperature up to 475 ℃。
