ABSTRACT
The (p, F, T) and some derived volumetric properties such as apparent molar volumes Vo of CaCl2 in ethanol, isothermal compressibility, and thermal expansion coefficients of (CaCl2 + C2H5OH) solutions at T ) (298.15 to 398.15) K and pressures up to p ) 40 MPa are reported. The density measurements were made at seven molalities of m ) (0.09327, 0.17427, 0.43788, 0.68992, 0.98955, 1.26564, and 1.55045) mol * kg-1 of CaCl2. An empirical correlation for the density of (CaCl2 + C2H5OH) as a function of pressure, temperature, and molality has been developed. This equation of state was used to calculate other volumetric properties such as isothermal compressibility and thermal expansion coefficients. The derived values of apparent molar volumes were extrapolated to zero concentration to calculate the values of apparent molar volumes (or partial molar volumes) at infinite dilution.
