“…The surface tension values are given in Table for the mixtures studied herein as a function of the mole fraction of the aromatic compound. A linear regression of surface tension versus temperature data found in the literature − for n -hexadecane yields the following relationship that was presented graphically in Luning Prak et al This equation predicts that the value of surface tension at 294.3 K should be 27.4 mN·m –2 , which agrees with the data reported herein of 27.3 ± 0.2 mN·m –2 . The linear regression of toluene surface tension data with temperature reported by Jasper predicts a surface tension of 28.4 mN·m –2 at 294.4 K, which agrees with the data reported herein of 28.4 ± 0.2 mN·m –2 .…”

In this work, the physical properties of binary mixtures of n-hexadecane with toluene or ethylbenzene were measured. Density and viscosity were measured at temperatures ranging from (293.15 to 373.15) K, and the speed of sound was measured at temperatures ranging from (293.15 to 333.15) K. Density mole fraction and temperature data were fit to a fourthorder polynomial. Viscosity mole fraction data were fit using the three-body McAllister model, while the viscosity deviations were fit to a Redlich−Kister type equation. For both two-component mixtures, the speed of sound at 293.15 K decreased as the mole fraction of the aromatic compound increased until a minimum was reached after which the speed of sound increased slightly to the value of the pure aromatic compound. The bulk modulus was calculated from density and speed of sound data. For both 2-component mixtures, the bulk modulus at 293.15 K decreased slightly as the mole fraction of the aromatic compound increased until a minimum was reached after which the bulk modulus increased to its highest value, which is the value for the aromatic compound. Flash points for the mixtures ranged from (278.5 to 408) K, and surface tension values ranged from (27.3 to 29.2) mN•m −1 .

New experimental surface tension data are reported for binary mixtures of dimethyl carbonate and diethyl carbonate with octane, decane, and 1,4-dimethylbenzene and 1,4-dimethylbenzene with octane and decane at 308.15 K and atmospheric pressure. These experimental results are compared with those reported in the literature at different temperature when they are available. The experimental results show that surface tension of these compounds depends systematically on temperature. The surface tension deviation calculated was fitted by the Redlich–Kister polynomial equation. The adjustable parameters obtained for each system are reported with the standard deviations between experimental and calculated values.

“…The Faizullin 20 approach was used to calculate reduced surface tensions of fluorocarbons, and the results were compared with the reduced surface tension calculated from experimental data measured in this work, as graphically presented in Figure 2. The n-octane 33 was included to test and validate the procedure, and a plot showing the deviations from the Faizullin estimated behavior is presented in Figure 3. The required experimental information is summarized in Table 5.…”

Surface Tension of Liquid Fluorocompounds

This work aims at studying the surface tension of some linear, cyclic, aromatic, and R-substituted perfluorocarbons. Despite its fundamental interest, information about this property for these compounds is scarce, and the available data are old and present strong discrepancies among each other. The measurements were carried out in the temperature range (283 to 327) K with the Du Nou ¨y ring method. The analysis of the experimental data shows that the molecular structure is an important factor in the surface behavior of the studied compounds since the aromatic fluorocompounds present the highest surface tensions, followed by the cyclic and substituted fluorocompounds. The linear n-perfluoroalkanes exhibit the lowest surface tension values, slightly increasing with the carbon number. The surface thermodynamic functions such as surface entropy and enthalpy were derived from surface tension values and are also reported. The experimental data were compared against the Faizullin correlation, and it is shown that this correlation describes the measured surface tensions with deviations inferior to 4 %.
