Data for: Measurement and Modeling for Poly(vinyl stearate) in Supercritical Fluids

In this study, the cloud-points were reported for poly(vinyl stearate) (PVS) in several fluids and mixed fluids consisted of carbon dioxide (CO2), propane, propylene, butane, 1-butene, and dimethyl ether (DME). The cloud-points for the PVS solution are measured using high-pressure apparatus with variable-volume view cell. The measured cloud-point pressures for all systems show a LCST-type phase behavior. The cloud-points for ternary systems consisted of CO2, DME, propylene, 1-butene, and PVS are measured over the range of temperature from 333 K to 453 K and the pressure from 35 MPa to 203 MPa.

在本研究中，报告了聚（硬脂酸乙烯酯）（PVS）在多种流体以及由二氧化碳（CO2）、丙烷、丙烯、丁烷、1-丁烯和二甲醚（DME）组成的混合流体中的云点。PVS溶液的云点采用具有可变体积视窗的高压装置进行测量。所有系统的测量云点压力均显示出LCST型相变行为。对于由CO2、DME、丙烯、1-丁烯和PVS组成的三元系统，其云点在温度范围为333 K至453 K，压力范围为35 MPa至203 MPa的范围内进行测量。
