| 摘 要： | 用精密自动绝热量热仪测定了乙酰氨基丙二酸二乙酯在78—395K温区的摩尔热容．根据实验测定的热容数据，用最小二乘法拟合计算出热容对温度的多项式方程，得到其相变焓、相变熵分别为34．295kJ·mol^-1、93．009J·K^-1·mol^-1．根据热力学函数关系式计算了其在80—395K温区每隔5K的热力学函数HT—H298．15]和ST-S298.15]．此外，用TG—DSC热分析技术进一步考查了该物质在相变区间的重复性和可靠性． |

| Abstract: | The Precision automatic Adiabatic calorimeter was adopted to measure the molar heat capacity of Diethylacetamidomalonate in 78 - 395 temperature range. The least squares fitting was adopted to calculate the polynomial equation of heat capacity and temperature, thus the phase transition entropies were obtained. They were 34. 295 kJ·mol^-1,93. 009 J·K^-1·mol^-1, respectively. TG-DSC thermal analytic technology was adopted to further investigate the repeativity and reliabity, of the material during the phase transition. |
