摘要：

Knowing high-pressure phase equilibrium is essential for the numerous applications of organic solvent-entrained supercritical carbon dioxide, as well for extraction as for antisolvent procedures. Phase equilibrium measurements on the carbon dioxide - methanol - dimethyl sulphoxide mixture are presented in the range of 308 K-323 K and 7.5 to approx. 11.5 MPa. Composition (mole fraction) was varied for each component in the ranges x(CO2) : 0.75 - 0.88; x(MeOH) : 0.042 - 0.21; and x(DMSO) : 0.025 - 0.12. Measurements were done using a static synthetic method based on the observations of cloud points and redissolution points. Measurement results were well approximated by the Peng-Robinson equation of state. (C) 2019 Elsevier B.V. All rights reserved.
