Abstract

This work presents phase equilibrium data of the ternary system CO2 + [bmim][BF4] + solute. Three different organic compounds were studied as the solute in the ternary system: 1-methyl-3-phenylpiperazine (MPhPz), 2-chloro-nicotinonitrile (NtN) and 2-(4-methyl-2-phenyl-1-piperazinyl)-3-pyridinecarbonitrile (PCN). Experiments were carried out in a pressure and temperature range of 1–14 MPa and 343.15–443.15 K, respectively. Samples were prepared with CO2 molar fractions of 0.10 until 0.40 for the system with NtN as the solute, and 0.20 for the other two systems for comparison. The data collected show how the various solutes affect the phase behavior of the binary system CO2 + [bmim][BF4], and at which conditions homogeneous phase can be obtained.
