“…Table does not contain the volumetric data of Jenner and Millet for 1-alkyl bromides , because some of them exhibit considerable disagreement with the more recent measurements and the recommended values evaluated by Frenkel et al at atmospheric pressure (for more details see Figure S1). Consequently, their precision at the elevated pressures might as well be regarded as questionable.…”

This study reports experimental density and sound velocity data of 1-chloroheptane and 1-iodoheptane at 291.45 ≤ T ≤ 413.15 K and 1 ≤ P ≤ 1961 bar along with the atmospheric pressure liquid densities at 223.15 ≤ T ≤ 423.10 K, sound velocities at 216.08 ≤ T ≤ 413.15 K, and isobaric heat capacities at 223.15 ≤ T ≤ 423.15 K. The evaluated values of the auxiliary thermodynamic properties are provided as well. An analysis performed in this study is based on the entire available high-pressure database of the medium chain 1-alkyl halides. It is demonstrated that, within its applicability range, the fluctuation theory based Tait-like equation of state (FT-EOS) predicts the high-pressure experimental data in a particularly accurate manner. The performance of the critical point based perturbed chain statistical association fluid theory (CP-PC-SAFT) is dependent on the robustness of the T c and P c data, whose appropriate values allow reliable predictions of densities until extremely high pressures, sound velocities, heat capacities, and the available binary high-pressure phase equilibria data. The entirely predictive CP-PC-SAFT + MYS (modified Yarranton–Satyro correlation) modeling framework yields reliable viscosity estimations of 1-alkyl chlorides and their mixtures. At the same time, it accurately predicts the pressure dependence established by the viscosity of 1-bromobutane only up to ∼2000 bar and it tends to underestimate this property for 1-iodoalkanes. Investigation of trends established by CP-PC-SAFT allows making some essential assumptions about the regularities characteristic for thermophysical properties of 1-alkyl halides at elevated pressures.

We present results of the experimental measurements of the isobaric heat capacity for 1-bromohexane, 1-bromoheptane, 1-bromooctane, 1-bromononane, 1-bromodecane, 1-bromoundecane, 1-bromododecane and 1-bromo-tetradecane at normal pressure and the speed of sound and the density for 1-bromotetradecane within the temperature range 298.15-423.15 K. These data on the isobaric heat capacity and the literature-based reference data for the density and the speed of sound were used to calculate the isothermal compressibility and the inverse reduced fluctuations. Based on the comparison of the results for pure n-alkanes and α, ω-dibromoalkanes, we discuss the influence of bromine atom on the volume fluctuations.

This work presents the results of systematic research of the sound speed and density of liquid bromoalkanes on the saturation line within the temperature range from (243.15 to 423.15) K. These results have been used for the calculation of isentropic compressibility β S , ratio of thermal capacities, and other thermophysical properties of the studied substances. Additionally, the Integral Constant of Dispersion Forces B for bromoalkanes has been estimated on the basis of the atom-atomic interactions model.
