摘    要:用差示扫描量热仪(DSC)测定了含能化合物3-硝基-1,2,4-三唑-5-酮(NTO)和碳酰肼(CHZ)在340~410 K温度区间内、苦味酸(PA)和二硝基苯酚(DNP)在330~360 K温度区间内的比热容,对所测温度区间内物质的比热容随温度变化的曲线进行了拟合,NTO和CHZ的比热容在所测温度区间内比热随温度变化符合一次函数:Cp=a bT,而DNP和PA符合三次函数:Cp=a bT cT2 dT3。NTO、CHZ、DNP、PA拟合曲线的相关度分别是0.9591、0.9730、0.9968和0.9972。

关 键 词:分析化学  差示扫描量热法(DSC)  比热容  3-硝基-1  2  4-三唑-5-酮(NTO)  碳酰肼(CHZ)  二硝基苯酚(DNP)  苦味酸(PA)

Abstract:The specific heat capacity(Cp) values of four energetic compounds,3-nitro-1,2,4-triazol-5-one(NTO),carbohydrazide(CHZ),2,4-dinitrophenol(DNP) and picric acid(PA),were determined by differential scanning calorim-eter(DSC).The least square method is applied to treat experimental data.In the range of 340-410 K,theCpversusTrelationship of NTO and CHZ can be expressed as a simple equation:CP=a bT.In the range of330-360K,theCpver-susTrelationship of DNP and PAcan be expressed as a cubic equation:Cp=a bT cT2 dT3.The R-Squares(COD) ofmeasured results of NTO,CHZ,DNP and PA,are 0.9591,0.9730,0.9968 and 0.9972,respectively.
Keywords:analytical chemistry  differential scanning calorimeter(DSC)  specific heat capacity  3-nitro-1  2  4-tri-azol-5-one(NTO)  carbohydrazide(CHZ)  4-dinitrophenol(DNP)  picric acid(PA)
