“…The validation was performed on points with temperatures and pressures very similar to those of the present work. Good agreement was observed with the data reported by Garg et al [14] and Zolin et al [12] and most of the data of Gylmanov et al [11]. Similar deviations can be obtained using Eq.…”

“…Their review covered papers published until 1993 for methanol to 1-decanol [6], and for 2-pentanol the revision included papers published up to 1997 [7]. Liquid densities for 1-pentanol at high pressure have been measured by Bridgman [8], Walsh and Rice [9], Sahli et al [10], Gylmanov et al [11], Zolin et al [12], Altunin and Konikevich [13], Garg et al [14], Wappmann et al [15], and Sülzner and Luft [16]; however, for 2-pentanol only the experimental densities by Sahli et al [10] and Wappmann et al [15] are reported in the literature. The number of data points (n), range of temperature and pressure, and compound purity for the data reported by the mentioned references are presented in Table I.…”

Compressed liquid densities of 1-pentanol and 2-pentanol have been measured from 313 to 363 K at pressures to 25 MPa. Measurements have been achieved using a vibrating tube densimeter. Water and nitrogen are the reference fluids to calibrate the densimeter. Measurements uncertainties are estimated to be ±0.03 K for temperatures, ±0.008 MPa for pressures and ±0.20 kg·m −3 for densities. Two volume-explicit equations with five and six parameters and the 11-parameter BWRS equation of state are used to correlate the experimental densities of 1-pentanol and 2-pentanol reported in this work. Statistical values for the evaluation of the correlations are reported. Comparisons with literature data are performed for the temperature and pressure ranges of the measurements.

A previously described method, based on considerations of hard-sphere theory, is used for the simultaneous correlation of the coefficients of viscosity, selfdiffusion, and thermal conductivity for the n-alcohols, from methanol to n-decanol, in excellent agreement with experiment, over extended temperature and pressure ranges. Generalized correlations are given for the roughness factors and the characteristic volume. The overall average absolute deviations of the experimental viscosity, self-diffusion, and thermal conductivity measurements from those calculated by the correlation are 2.4, 2.6, and 2.0%, respectively. Since the proposed scheme is based on accurate density values, a Tait-type equation was also employed to correlate successfully the density of the n-alcohols. The overall average absolute deviation of the experimental density measurements from those calculated by the correlation is +0.05%.

A density measurement system was developed using a vibrating tube densimeter prototype for high temperature and high pressure (DMA-HDT). Fully automatic density measurements over a large temperature and pressure range were realized with the help of the specially developed controlling software. Currently, the unit is applicable for temperatures from 298 K to 523 K and pressures from atmospheric pressure up to 100 bar. The estimated total error in the density measurements is 0.0002 g/cm 3 .
