Abstract


Pressure, density and temperature (p, ρ, T) data and apparent molar volumes, Vfo, of aqueous calcium acetate solutions Ca(CH3COO)2(aq) over a wide range of temperatures from 273.15 to 353.15 K, pressures up to p = 100 MPa and molalities m, of 0.04918, 0.09367, 0.23797, 0.36365, 0.85923, 1.06930, 1.35223 and 1.81668 mol×kg-1 of Ca(CH3COO)2 are reported. The combined expanded uncertainty of the density (ρ) measurements at the 95 % confidence level with a coverage factor of k = 2 was estimated to be Uc(ρ) = ±0.3 kg∙m‐3. The measurements were realized with an Anton Paar DMA HPM vibration tube density meter. The system was calibrated using double-distilled water, aqueous NaCl solutions, methanol, toluene and acetone. An equation of state for fitting of the (p, ρ, T) data of aqueous calcium acetate was developed as a function of pressure, temperature and molality. After a thorough analysis of literature values and validity of the constructed equation of state, various thermophysical properties, such as isothermal compressibility, isobaric thermal expansibility, differences in isobaric and isochoric heat cap­acities, thermal pressure coefficient and internal pressure at the investigated state parameter int­ervals were calculated.
