摘要：

The aim of this research to investigate thermophysical properties of alkoxyethanols with alcohols, including densities, speeds of sound, and refractive index of five binary mixtures constituted by 2-ethoxyethanol (2EE) + methanol, or ethanol, or propan-1-ol, or propan-2-ol, or butan-2-ol, that have been measured at the temperatures: (293.15, 303.15, 313.15 and 323.15) K, over the entire composition range and at pressure of p = 0.1 MPa. The Cubic Plus Association equation of state (CPA-EOS) has been used to correlate the measured properties. From the measured data, excess/derived properties: excess molar volume, isentropic compressibility, deviation in isentropic compressibility and deviation in refractive index were calculated and correlated using the Redlich Kister equation. The results obtained from the work have been discussed in terms of the nature of molecular interactions between the components of the mixture.
