Densities of pure propan-1-ol have been measured in the liquid phase with a modified high pressure-high temperature Anton-Paar vibrating-tube densimeter (model DMA 5000). Measurements were made at six isotherms (298.15, 323.15, 348.15, 373.15. 398.15, and 423.15 K) as a function of pressure. The range of pressure was 0.1-40 MPa. The total uncertainty of density, temperature, and pressure measurements were estimated to be less than 0.15 kg m-(3), 15 mK, and 5 kPa, respectively. The uncertainties reported in this paper are expanded uncertainties at the 95% confidence level with a coverage factor of k = 2. Values of saturated densities were determined by extrapolating experimental P-p data to the vapor pressure at fixed temperature. The measured values of density were used to calculate the derived properties such as isothermal compressibility (K-T.), thermal expansion coefficient (alpha(p)), isochoric (C-v) and isobaric (C-p) heat capacities, and sound velocity (W). All measured and derived properties were compared in detail with the data reported in literature. Measured values of p, rho, and T were used to develop Tait and polynomial type equations of state. The quality and predicting capability of the Tait type equation of state was examined by comparing with direct measured Values of heat capacity at constant volume and constant pressure, speed of sound, isothermal compressibility, etc. (C) 2008 Elsevier B.V.
