在几个温度下实验测量氨+硫氰酸钠混合物的几种热物理性质：密度为（269.4至350.9）K，动力粘度从（269.8至369.5）K，等压热容从（304.17 ~ 364.15）K，均为常压3 MPa，汽液平衡范围为（253.1 ~ 393.1）K。在氨质量分数为0.35 ~ 0.90的组成范围内测量了所有性能。所使用的实验技术是振动管密度计，活塞式粘度计，热通量Calvet型量热计，和静态的方法，分别。测量的数据进行了相关的温度和组成的函数，使用经验方程，并与文献值进行了比较。
Several thermophysical properties were experimentally measured for the ammonia + sodium thiocyanate mixtures at several temperatures: density from (269.4 to 350.9) K, dynamic viscosity from (269.8 to 369.5) K, and isobaric heat capacity from (304.17 to 364.15) K, all them at a constant pressure of 3 MPa, and vapor–liquid equilibria from (253.1 to 393.1) K. All properties were measured in a range of composition from 0.35 to 0.90 in ammonia mass fraction. The experimental techniques used were a vibrating-tube densimeter, a piston-style viscometer, a heat flux Calvet-type calorimeter, and a static method, respectively. The measured data were correlated as a function of temperature and composition using empirical equations and were compared with literature values.
