Abstract :

The phase behaviour of carbon dioxide + ethanol system has been investigated mainly in terms of the variables pressure, temperature and composition. With few exceptions the densities of the coexisting phases are neglected and even when measured, they range in temperatures between 291,15 K to 313,15 K. For a complete description of the phase equilibrium in this system further measurements are needed, up to temperatures in the neighbourhood of the critical temperature of ethanol. In this study the densities and mutual solubility of carbon dioxide and ethanol were determined at the temperatures 333,15 K, 353,15 K, 413,15 K and 453,15 K and pressures from 4 MPa up to 14,5 MPa. The critical densities curve was constructed for the whole concentration range.
