dc.description.abstractEn | The phase behaviour of carbon dioxide/Vegetable Based Epoxidized Oils (VBEO) mixtures has been investigated at three different temperatures (40, 70 and 100°C) and pressures ranging between 0.1 and 20 MPa. The measurements have been performed using an efficient in-situ FTIR method that allowed us to determine the variation of the concentration of each component in the two phases (CO2 rich phase and VBEO rich phase) as a function of temperature and pressure. Several epoxidized mono-, di- and tri-glyceride derivatives have been tested. The solubility of these epoxidized oils have been investigated in the CO2 rich phase and in the CO2 sorption and the resulting swelling of the VBEO rich phase. From these concentration measurements, we could establish the pressure-composition phase diagrams of these VBEO/CO2 binary mixtures. The three monoglyceride derivatives studied were found to be more soluble in CO2 and have a higher percentage of swelling than the VBEO which have a higher molecular weight. However, it was found that a significant amount of CO2 was incorporated in all these VBEO at relatively moderate pressures. Thus, we expect these VBEO to be good candidates for performing carbonation reaction to generate in good yields vegetable-based cyclic carbonates as polyurethane precursors. | |
