Abstract

High-pressure vapor-liquid equilibrium (VLE) data were measured for binary CO₂-alcohol systems (e.g. methanol, ethanol, 2-methoxyethanol, and 2-ethoxyethanol) at various isotherms (313.15-345.15K). The quantitative VLE data and mixture critical conditions were measured using a new design for a circulation VLE system. The measure data were correlated by the classical Peng-Robinson and the multi-fluid nonrandom lattice fluid hydrogen-bonding (MF-NLF-HB) equation of state. The MF-NLF-HB model was formulated previously by the present authors based on the proton donor-acceptor principle to the hydrogen-bonding interaction in CO₂-alcohol systems. For the measured and calculated data of CO₂-alcohol systems, the relative accuracy of the data was discussed.
