Resumen:
The use of mixtures of propane + CO2 for the extraction of natural products can offer special properties regarding solvent power, selectivity and safety. For the case of extraction of vegetable oils from grounded seeds, previous studies have shown that it is possible to obtain complete miscibility of the vegetable oil with the propane + CO2 mixture keeping the mixture below the flammability limits (Hegel et al, 2006). A strategy for mixture design at different temperatures to comply with the requirements of complete miscibility and non flammability is presented, on the basis of the phase equilibrium properties of the mixtures of vegetable oils + propane + CO2.
