具有高全球变暖潜能值（GWP）的制冷剂将逐步淘汰，这刺激了寻找替代流体的研究。2，3，3，3-正丙基-1-烯（R1234 yf）和反式-1，3，3，3-正丙基-1-烯（R1234 ze（E））的化学和热物理性质使它们成为有希望的候选物。精确的热物理性质对于设计和开发使用这些化合物的有效工艺至关重要。本文报道了2，3，3，3-正丙基-1-烯（R1234 yf）在（243 ~ 363）K温度范围内从饱和压力到30 MPa的粘度。关于R1234 ze（E），在（243和373）K之间的温度下从饱和压力直到30 MPa进行测量。使用振丝粘度计测量粘度，组合扩展不确定度约为2.0%。基于硬球模型的方案被用来关联实验结果。(C)2013爱思唯尔有限公司保留所有权利。
The refrigerants with high global warming potential (GWP) will be phased out, which has stimulated research to find replacement fluids. The chemical and thermophysical properties of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) have made them the promising candidate. Accurate thermophysical properties will be essential to design and develop efficient processes that use these compounds. In this work, the viscosity of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) in the temperature of (243 to 363) K from saturated pressures up to 30 MPa was reported. With regard to R1234ze(E), measurements were performed at temperatures between (243 and 373) K from saturated pressures up to 30 MPa. The viscosity was measured using a vibrating-wire viscometer with a combined expanded uncertainty of about 2.0%. The scheme based on a hard-sphere model was used to correlate the experimental results. (C) 2013 Elsevier Ltd. All rights reserved.
