摘要: 基于熔盐混合物与含醇溶液的某些相似性,将含醇溶液的过量焓方程推广到熔盐混合物.该方程由物理和化学作用两部分贡献组成,具有良好的灵活性和通用性,对149种熔盐混合物的过量焓计算结果表明,与实验值的平均绝对误差为0.29%,最大误差不超过1.8%.

Abstract: The excess enthalpies equation of solutions containing alcohol established by the authors’previous work is extended to molten salt mixtures because they have some similarities. This equation includes physical and chemistry contributions, and has good flexibility and generality. The calculation results of excess enthalpies for 149 molten salt mixtures show average absolute deviation(AAD) with experimental values 0.29%, and maximum deviation less than 1.8%.
