“…The density values for pure compounds, ACN, DMHA, DMCHA, TMPDA, TMBDA, and PMDETA, at T = 288.15–323.15 K and 101 kPa are reported and compared with literature values in Table S1. The deviations of 100(ρ Exp – ρ Lit )/ρ Exp are calculated, and the results are presented in Figure . − The measured density values are in good agreement with literature works, and the discrepancies are ≤0.15% (except for refs and ). All the differences may be attributed to the purity of compounds and the methods of measurement.…”

In this work, the volumetric properties of five binary systems based on different tertiary amines and acetonitrile were investigated at temperatures ranging from 288.15 to 323.15 K and 101 kPa. The studied amines were N,Ndimethylhexylamine, N,N-dimethylcyclohexylamine, N,N,N′,N′-tetramethyl-1,3propanediamine, N,N,N′,N′-tetramethyl-1,4-butanediamine, and pentamethyldiethylenetriamine. According to the measured density values, the thermal expansion coefficient (α p )and excess properties including the excess molar volume (V m E ), apparent molar volume (V φ,i ), partial molar volume (V i ), and excess partial molar volume (V̅ i E ) were calculated. All the properties were further discussed from the view of intermolecular interactions. Moreover, the excess molar volume V m E was correlated by the Redlich−Kister equation.

The density of five 1-alcohols (1-hexanol, 1heptanol, 1-octanol, 1-nonanol, and 1-decanol) was measured using a vibrating-tube densimeter at pressures of up to 120 MPa for temperatures between 298.15 and 423.15 K. The relative expanded uncertainty of the experimental data is below 0.2%. The new results significantly extend the available literature data. The density of the five alcohols was modeled using four molecular-based equations of state (EOSs), namely PC-SAFT, SAFT-VR Mie, soft SAFT, and CPA. New component-specific EOS models were parametrized for all considered EOSs and substances using vapor−liquid equilibrium data from the literature and the density data from this work. The resulting EOS models describe the density with deviations of about 0.2−1.5%. For the thermal second-order derivative properties, the relative deviations were 10−50% for the isothermal compressibility and 5−35% for the thermal expansion coefficient. Also, the extrapolation behavior of the EOS models was assessed. Overall, the best results were obtained from the SAFT-VR Mie EOS.
