Etude par spectrométrie de vibration des interactions moléculaires dans le solvant supercritique universel CO2/éthanol

Abstract : This work is aimed at the understating of the microscopic organisation of the CO2/ethanol supercritical mixture, considered as an universal solvent in industrial applications (fractionation of polymers). The methodology is based upon the use of vibrational spectroscopy (Infrared and Raman) and the theoretical analysis of the experimental results from ab-initio calculations and analytical approaches. The heat fluids as well as the CO2/ethanol mixture were studied. The analysis of CO2 symetric vibrational stretching mode in the temperature and the density range 28
