Density measurements of liquid 2-propanol at temperatures between (280 and 393) K and at pressures up to 10 MPa
Liquid densities for 2-propanol have been measured at T = (280, 300, 325, 350, 375, and 393) K from about atmospheric pressure Up to 10 MPa using a vibrating tube densimeter. The period of vibration has been converted into density using the Forced Path Mechanical Calibration method. The R134a has been used as reference fluid for T <= 350 K and water for T > 350 K. The uncertainty of the measurements is lower than +/-0.05%. The measured liquid densities have been correlated with a Starling BWR equation with an overall AAD of 0.025%. The same BWR equation agrees within an AAD lower than 0.2% with the experimental values available in the literature over the same temperature and pressure range. (C) 2008 Elsevier Ltd.
