PVTx‐Properties and virial coefficients of the water‐n‐hexane system

PVTx-data for the water-n-hexane system are reported in this paper. The data cover a temperature range from 523 to 623 K and pressure range from 2 to 16 MPa at different concentrations. The low pressure compressibility measurements were used to determine second and third virial coefficients for the water-n-hexane system. The values of the parameters in the square well potential are derived from virial coefficients data for pure components and binary mixtures water-n-hexane.
