摘要
采用激光监测动态法精确测定了N-溴代琥珀酰亚胺在水、乙醇、丙酮中的溶解度,绘出溶解度曲线,并使用λh方程对实验数据成功地进行了关联。三个体系共41个数据点,实验值与计算值总的平均相对误差为0.90%,体现了λh方程的普遍适用性。实验结果不仅完善了热力学数据,而且有利于N-溴代琥珀酰亚胺的生产和应用。
The solubility data of N-bromosuccinamide in water, ethanol and acetone are measured using dynamic method with laser-monitoring observation. The experimental data are correlated successfully with λh equation, and the solubility curves are protracted. The average relative error between the calculated values and the experimental values of 41 data points were 0.90%. It is indicated that the λh equation make good suitability. This study not only enrich the thermodynamic database, but also is available in the production and application of N-bromosuccinamide.
