摘要：

Phase equilibria data for the system ethanol/carbon dioxide for T = 313.15 K and pressures up to p = 7.9 MPa are presented. The measurements were made by Raman spectroscopy without the extraction of probes from the autoclave. To the authors knowledge this is the first use of Raman spectroscopy for phase equilibria investigations at high pressure with supercritical carbon dioxide. The data show very good agreement with literature data.
