摘　　要：R1233zd(E)具有无毒、环保、不可燃等优点,而离子液体具有较宽的液体温度范围和良好的物理化学性质。R1233zd(E)和离子液体相结合可以成为一种优良的吸收式制冷工质对。测量了R1233zd(E)在[HMIM][PF6]离子液体中的溶解度和扩散系数,温度测量范围为303.2~343.2K,压力测量范围为23~140kPa。为了方便工业化应用,采用NRTL方程和Arrhenius方程对实验结果进行了关联,计算结果和实验数据之间的平均偏差和最大偏差分别为2.45%和6.13%。R1233zd (E) has the advantages of non-toxic, environmentally friendly, non-flammable, and the ionic liquid has a wide liquid temperature range and good physicochemical properties. The combination of R1233zd(E) and ionic liquids can be an excellent pair of absorption refrigeration. In this paper, the solubility and diffusion coefficient of R1233zd (E) in [HMIM][PF6] ionic liquid were measured. The temperature measurement range was 303.2-343.2 K, and the pressure measurement range was 23-140 kPa. In order to facilitate industrial application, the experimental results were correlated by NRTL equation and Arrhenius equation. The average deviation and maximum deviation between the calculated results and experimental data were 2.45% and 6.13%, respectively.
