“…This conclusion can be verified by the well-known interrelation between the strength of intermolecular interactions and the cohesive energy density , determined by the molar enthalpy of vaporization. The latter allows estimating the internal pressure in nonassociating liquids according to …”

“…Substituting eq into eq while obtaining the experimental data on Δ vap H m of 1-chlorononane from Bolotnikov and Neruchev yields the line labeled on Figure as 1-chlorononane ( H ). As seen, it is situated in the near vicinity to the pertinent line obtained from eq .…”

“…As seen, it is situated in the near vicinity to the pertinent line obtained from eq . At the same time, it has been demonstrated that Δ vap H m can be accurately estimated by a model considering the overall mean energy constants of attractive forces in liquid chlorinated alkanes as a weighted combination of energies of the pairwise interactions between hydrogen and chlorine atoms. According to this approach, the weight is dependent on the ratio between hydrogen and chlorine atoms in this “mixture” and on the ratio between the constants of the pair potential of their dispersion forces.…”

This study reports the experimental density and speed of sound data of 1-chlorononane along seven isotherms from 293.15 to 413.15 K at pressures from saturation up to 196.1 MPa. The pertinent isothermal compressibility and isobaric coefficient of expansion data have been obtained by numerical differentiating of densities. In addition, the saturated liquid densities have been measured from 253.15 to 443.15 K, isobaric heat capacities from 248.15 to 448.15 K, and speeds of sound from 246.88 to 457.25 K. These results have been interpolated by polynomials to obtain the saturated liquid isobaric coefficient of expansion, adiabatic and isothermal compressibility, isochoric heat capacity, and internal pressure data. Performances of three predictive approaches having different degrees of complexity, namely the Critical Point-based Perturbed Chain Statistical Association Fluid Theory, the Statistical Association Fluid Theory of Variable Range Mie Potential parametrized by a Corresponding States approach of Mejía et al. (Ind. Eng. Chem. Res. 2014, 53, 4131), and the fluctuation theory-based Tait-like equation of state have been examined. The latter model has a superiority in estimating of the high-pressure data; however, unlike both statistical association fluid theory approaches, it utilizes the saturated liquid data. It has also been demonstrated that all the models successfully predict various phenomena related with replacement of hydrogen by chlorine in n-nonane molecule.

“…The analysis of presented values of | E P | leads to the conclusion that in the liquid bromoalkanes, as well as in n -alkanes and chloroalkanes, the energy of intermolecular forces is proportional to the square of its density. The discrepancies between the results from eqs and are observed at low temperatures and high densities, probably because of the influence of repulsive forces.…”

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.
