Novel experimental data and theoretical calculations of bubble point pressure and liquid-phase viscosity for a propane (R-290)/POE ISO 22 binary system are presented. The experimental setup consisted of an oscillating-piston viscometer connected in series with a synthetic variable-volume PVT cell. Experimental data were acquired for R-290 with mole fractions ranging from 0.2 to 0.8, temperatures between 283 and 353 K and pressures up to 22.5 bar. The phase equilibrium (bubble point pressure) was modelled using the Peng and Robinson (1976) and PC-SAFT (Gross and Sadowski, 2001) equations of state, while the liquid mixture viscosity data were predicted with the generalized friction theory (f-theory) of Quiñones-Cisneros and Deiters (2006). The absolute average deviations associated with the phase equilibrium and liquid viscosity calculations were 8.39% and 6.56% (Peng-Robinson and PC-SAFT), and 24.77% (generalized f-theory).

提出了丙烷（R-290）/ POE ISO 22二元体系的新的实验数据和沸点压力和液相粘度的理论计算。实验装置包括与合成可变体积PVT电池串联的振荡活塞粘度计。获得了R-290的实验数据，其摩尔分数为0.2至0.8，温度在283至353 K之间，压力高达22.5 bar。使用Peng和Robinson（1976）和PC-SAFT（Gross and Sadowski，2001）状态方程对相平衡（气泡点压力）进行建模，而液体混合物的粘度数据则通过广义摩擦理论（f理论）进行预测。 ）（Quinones-Cisneros and Deiters）（2006）。与相平衡和液体粘度计算相关的绝对平均偏差为8。
