The liquid density of five liquid
1H,1H-perfluorinated alcohols (CF3(CF2)
n−1CH2OH n = 2, 3, 4, 5, 6) was measured as a function
of pressure
(0.1–70
MPa) and temperature (293.15–313.15 K). The corresponding isothermal
compressibility and isobaric thermal expansivity coefficients were
calculated from the experimental data. The results are compared with
data from the literature for the equivalent hydrogenated alcohols.
Atomistic molecular dynamics simulations were also performed, providing
molecular-level insight into the experimental results, in particular
about the H-bond network of the perfluorinated alcohols and the effect
of pressure on the organization of the liquid.
