Abstract

This work presents new phase equilibrium data of {CO2 + 2-ethyl-1-hexanol} and {CO2 + 2-methyl-2-propanol} systems with or without glycerol. The static synthetic method using a variable-volume view cell was utilized to measure vapor-liquid equilibrium saturation points at temperatures from 343 K to 393 K and at pressures up to 20 MPa. The phase transition pressure measurements were carried out by injecting a known amount of carbon dioxide into a mixture of [0.0087 glycerol + 0.9913 (2-ethyl-1-hexanol or 2-methyl-2-propanol)]. This amount of added glycerol did not significantly affect vapor-liquid transition pressures, compared to binary systems without glycerol. The Peng-Robinson equation of state was used to correlate the experimental phase equilibrium data.
