Speed of Sound, Densities, and Isentropic Compressibilities of Liquid 1-Bromoalkanes at Temperatures from (243.15 to 423.15) K

Abstract

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.

Isobaric Heat Capacity, Isothermal Compressibility and Fluctuational Properties of 1-Bromoalkanes

“…The latter is reflected in the value of the internal pressure [25,26,27]. At the same time, it has been shown [11] for 1-bromoalkanes that the averaged energy of intermolecular interaction within the studied liquids can be calculated as |E| = Bρ 2 with…”

“…These data and the reprocessed data on the speed of sound and the density given in [11,9] were approximated by the quadratic…”

“…Recently, a variety of data have been obtained for the series of consequent lengths in chains of bromo-substituted alkanes and different numbers of bromine atoms per molecule [8,9,10,11,12,13]. Some gaps in these datasets are filled and presented in the article.…”
