摘要:
采用差示扫描量热法和热重分析法对反式阿魏酸的熔点、熔化热、分解温度等性质进行了实验研究,确定了DSC-60差示扫描量热仪测定反式阿魏酸的条件,即在升温速率10℃·min-1,氮气流速20 mL·min-1的条件下,分析样品,可测得的较准确的DSC曲线,并在此条件下测得反式阿魏酸熔点为174.64℃,熔化热为150.00 J·g-1,分解温度为190℃.在氮气气氛条件下,采用DTG-60差热-热重分析仪测定了阿魏酸的DTA-TGA谱图,在190℃-260℃之间有明显失重,证实了阿魏酸在氮气气氛下190℃开始
Abstract:
The melting point, heat of melting, decomposition temperature and other properties of trans-ferulic acid were experimentally studied by differential scanning calorimetry and thermogravimetric analysis method, and the conditions for the determination of trans-ferulic acid by DSC-60 differential scanning calorimeter were determined, that is, under the conditions of a heating rate of 10°C·min-1 and a nitrogen flow rate of 20 mL·min-1, the sample could be analyzed to obtain a more accurate DSC curve, and under these conditions, the melting point of trans-ferulic acid was 174.64 °C and the heat of melting was 150.00 J·g-1. The decomposition temperature was 190 °C. Under the condition of nitrogen atmosphere, the DTA-TGA spectrum of ferulic acid was determined by DTG-60 differential thermal-thermogravimetric analyzer, and there was significant weight loss between 190 °C and 260 °C, which confirmed that ferulic acid began at 190 °C in nitrogen atmosphere
