“…There have been extensive studies on the thermophysical properties of mixtures containing organic compounds in order to understand their behavior at both the macroscopic and microscopic level. − Specifically, several excess properties for {α,ω-dichloroalkane + linear alkane} were found to be sensitive to the intramolecular effect denominated proximity effect . − Excess molar Gibbs free energy , excess molar enthalpy , and excess molar volume have been the most studied properties and to a less extent the excess isobaric molar heat capacity . However, little is known about other second-order excess properties such as the isochoric molar heat capacity , isentropic and isothermal compressibility, and isobaric thermal expansivity due mainly to the scarcity of experimental data.…”

Densities and speeds of sound for {(1,5-dichloropentane or 1,6-dichlorohexane) + dodecane} in the temperature interval (278.15 to 328.15) K were determined using a tube vibrating densimeter and sound analyzer (Anton-Paar DSA-48). Isobaric heat capacities per unit volume for the same systems were measured in the temperature interval (283.15 to 323.15) K by means of a micro DSC II calorimeter using the scanning method. In all cases, measurements were made at atmospheric pressure. From these data, the molar volumes, isobaric and isochoric molar heat capacities, isentropic and isothermal compressibilities, and isobaric thermal expansivities as well as their excess quantities were calculated. Some comments related to the influence of the well-known effects of {polar + long alkyl chain linear alkane} on excess properties were included.

“…An example is (propane + ethanol) (10) where (1H E m /1p) T is small at T = 298.15 K, but large at T =363.15 K, a temperature less than 7 K below the critical temperature of propane. The effect of pressure on H E m becomes very large when the alkane is a supercritical fluid, such as in (ethane + propan-1-ol), (11) where (1H E m /1p) T is almost two powers of 10 larger than in (butane + propan-1-ol) at the higher temperatures. …”
