Abstract
The (p,ρ,T) properties and apparent molar volumes Vφ
of LiNO3 in ethanol at temperatures T = (298.15 to 398.15) K
and pressures up to p = 40 MPa are reported. The vibration tube densimeter
method used during the experiments. The experiments were carried out at
molalities of m = (0.12071, 0.26234, 60237, 0.97956, 1.83765, 2.62045
and 3.27773) mol kg–1 using lithium nitrate. An empirical correlation
for the density of (LiNO3 + C2H5OH) with
pressure, temperature and molality has been derived. The short form of equation
of state was developed for the technical calculations. Apparent molar volume and
thermal properties of LiNO3 in ethanol were calculated using the
equation of state.
