摘要:
用差示扫描量热法(DSC)和热重法(DTA-TGA)对肌醇进行了热分析研究:用DSC法测得了肌醇的熔点为227.67℃,熔化热为256.67 J·g-1,用DSC和DTA-TGA联合分析得到肌醇分解温度在300℃以上.同时确定了DSC-60差示扫描量热仪测定肌醇的实验条件,即在升温速率10℃·min-1,氮气流速30 ml·min-1的条件下,分析肌醇样品可得到较好的DSC曲线.
Abstract:
Inositol was studied by differential scanning calorimetry (DSC) and thermogravimetric method (DTA-TGA): the melting point of inositol was 227.67 °C, the heat of melting was 256.67 J·g-1 by DSC method, and the decomposition temperature of inositol was above 300 °C by combined analysis of DSC and DTA-TGA. At the same time, the experimental conditions for the determination of inositol by DSC-60 differential scanning calorimeter were determined, that is, under the conditions of temperature increase rate of 10°C·min-1 and nitrogen flow rate of 30 ml·min-1, a good DSC curve could be obtained by analyzing inositol samples.
