Vapor–liquid equilibrium (VLE) property measurements for 2,3,3,3-tetrafluoroprop-1-ene (HFO-1234yf) + butane (HC-600) were carried out. The range of temperature is from 283.15 to 323.15 K, and the corresponding range of pressure is from 0.148 to 1.30 MPa. The experimental uncertainties in pressure, temperature, and mole fraction are estimated within 3.5 kPa, 5 mK, and 0.003, respectively. Peng–Robinson (PR) equation of state coupling with Wong–Sandler (WS) mixing rule and van der Waals (vdW) mixing rule were used to correlate the experimental VLE data of HFO-1234yf/HC-600. Both of the two models reproduce the VLE property of HFO-1234yf/HC-600 with high accuracy, and PR–WS-NRTL model gave slightly more accurate VLE calculations. Azeotropic behavior was found at high mole fraction of HFO-1234yf.

2,3,3,3-四氟丙-1-烯+丁烷在283.15至323.15 K温度下的汽液平衡测量

进行了2,3,3,3-四氟丙-1-烯（HFO-1234yf）+丁烷（HC-600）的汽液平衡（VLE）性能测量。温度范围为283.15至323.15 K，相应的压力范围为0.148至1.30 MPa。估计压力，温度和摩尔分数的实验不确定性分别在3.5 kPa，5 mK和0.003之内。Peng–Robinson（PR）状态方程，Wong-Sandler（WS）混合规则和van der Waals（vdW）混合规则用于关联HFO-1234yf / HC-600的实验VLE数据。这两个模型都以较高的精度再现了HFO-1234yf / HC-600的VLE属性，而PR–WS-NRTL模型则给出了更为精确的VLE计算。在HFO-1234yf的高摩尔分数下发现共沸行为。
