本文报道了两种氟化物质的压力-密度-温度和气-液界面张力-温度关系的实验数据，这两种氟化物质满足目前热力循环技术材料和工质对零臭氧消耗潜能值和有限全球变暖潜能值的要求。用定容法测定了1，1，1，3，3-五氟丁烷（HFC-365 mfc）和1，1，1，2，2，3，3-七氟-3-甲氧基丙烷（HFE-347 mcc，HFE-7000）在温度（208 ~ 353）K、压力（1 ~ 40）MPa下的数据。因此，实验p-ρ-T数据所覆盖的温度-压力区域对于这两种物质来说已经被大大扩展。在0.95置信水平下，所报告密度数据的综合不确定性在温度区间的下端取最大值，即HFC-365 mfc为1.0 kg·m-3（0.75·10-3ρ），HFE-347 mcc为1.5 kg·m-3（10-3ρ）。报告数据的均方根偏差来自…
Experimental data on the pressure–density–temperature and air–liquid interfacial tension–temperature relations are reported for two fluorinated substances that meet the present requirements of the technological materials and working media for thermodynamic cycles to have zero ozone depletion potential (ODP) and limited global warming potential (GWP). The data for 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and 1,1,1,2,2,3,3-heptafluoro-3-methoxy-propane (HFE-347mcc, HFE-7000) were obtained with a constant volume apparatus at temperatures from (208 to 353) K and at pressures from (1 to 40) MPa. Thus, the temperature–pressure region covered with experimental p–ρ–T data has been substantially extended for both substances. The combined uncertainty at the 0.95 confidence level of the reported density data takes its maximum value at the lower end of the temperature interval, namely 1.0 kg·m–3 (0.75·10–3ρ) for HFC-365mfc and 1.5 kg·m–3 (10–3ρ) for HFE-347mcc. The root-mean-square deviation of the reported data from...
