“…On the other hand, as already mentioned, the results of Sun et al at low temperatures 9 (203 to 263 K) are not consistent with their own data at higher temperatures 8 (263 to 333 K), the differences being more significant at high pressures.

“…There have been several efforts describing the effect of temperature and pressure on the hydrogen bond strength of methanol. A number of theoretical and experimental studies have been performed to understand the thermodynamic, structural, and dynamic properties of methanol at high densities, among others, correlations of the equation of state; − measurements of the dielectric constant, , refractive index, viscosity, , and elastic properties; , and computer simulations. , However, efforts to understand the high-pressure behavior of methanol have been focused at room temperature and above. The limited number of reliable high-pressure measurements available to date at temperatures close to the melting line is somewhat surprising.…”
We present direct measurements of the isothermal compressibility (κ
T
) and thermal expansion coefficient (α
p
) of
liquid methanol using an expansion technique. The measurements of κ
T
were carried out along six isotherms
from (208.17 to 298.16) K at pressures up to 101 MPa. For α
p
, we have measured four isobars from (0.59 to
80.03) MPa from 195 K up to 300 K. Our experimental results of α
p
(T) for the 0.59 MPa isobar exhibit a minimum
around 224 K. A clear shift of the minimum to higher temperatures is observed as the pressure increases along
the different isobars. Interestingly, the minima for the isobars of α
p
(ρ) take place within a narrow range of densities,
around 26.5 mol·dm-3 (about 3.15 times the critical density).
