Compressed liquid densities of carbon dioxide + ethanol mixtures at four compositions via a vibrating tube densimeter up to 363 K and 25 MPa

Compressed liquid densities of carbon dioxide and ethanol mixtures at four compositions from 313 to 363 K and up to 25 MPa were determined using a vibrating tube densimeter. The pressure measurements were conducted in a equilibrium cell using 25 MPa Sedeme pressure transducer. The results show the presence of excess volume for the carbon dioxide and ethanol mixtures at four composition with corresponding uncertainities not exceeding ±2.5%.
