Excess molar volumes, excess molar enthalpies and refractive index deviations for binary mixtures of propan-1-ol, butan-1-ol and pentan-1-ol with 2,2,4-trimethylpentane at 298.15K

Density, Viscosity, and Freezing Point for Four Binary Systems of n-Dodecane or Methylcyclohexane Mixed with 1-Heptanol or Cyclohexylmethanol

“…Subsequently, Figure panels c and d present comparisons of the excess molar volumes calculated in this work with literature values. , In Figure c, the V m E values from this work are in good agreement with the literature values at 298.15 K. Figure d shows that the values of V m E from this work and the literature have similar trends for methylcyclohexane +1-heptanol at 303.15 K. A comparison of the densities of pure samples in this work with those from the literature shows that the maximum deviation is 0.012%. The slight increase in the density value leads to a significant change in the derived value of V m E Figure includes comparisons of density and excess molar volume, respectively, of dodecane +1-heptanol system at 298.15 K with data available in literature. , The experimental values in this work are in good agreement with literature data.…”

“…The slight increase in the density value leads to a significant change in the derived value of V m E . 10 Figure 2 includes comparisons of density and excess molar volume, respectively, of dodecane +1-heptanol system at 298.15 K with data available in literature. 11,12 The experimental values in this work are in good agreement with literature data.…”

Densities and Viscosities of Binary Mixtures of 2,2,4-Trimethylpentane + 1-Propanol, + 1-Pentanol, + 1-Hexanol, and + 1-Heptanol from (298.15 to 323.15) K

“…Figures to show comparisons of the excess molar volumes obtained in this work with literature values for 2,2,4-trimethylpentane + 1-propanol at (298.15 and 303.15) K, 2,2,4-trimethylpentane + 1-pentanol at 298.15 K, and 2,2,4-trimethylpentane + 1-heptanol at 308.15 K, respectively. Figure shows that the values of V E from this work and the literature have similar trends for 2,2,4-trimethylpentane + 1-propanol at 298.15 K, with our results falling between Faneite’s data and Hwang’s values . For the 2,2,4-trimethylpentane + 1-propanol system at 303.15 K (Figure ) and the 2,2,4-trimethylpentane + 1-heptanol system at 308.15 K (Figure ), the V E values from this work are in good agreement with the literature values. , As shown in Figure , our excess molar volumes for the 2,2,4-trimethylpentane + 1-pentanol system at 298.15 K agree with the literature data at 2,2,4-trimethylpentane mole fractions lower than 0.5, while the maximum difference is 0.106·10 –6 m 3 ·mol –1 at a mole fraction of 0.8.…”

“…However, the thermodynamics and transport properties for 2,2,4-trimethylpentane + alcohol systems are still scarce in the literature. Densities of mixtures of 2,2,4-trimethylpentane with 1-propanol and 1-pentanol have been measured at 298.15 K by Faneite et al Hwang et al measured the density of 2,2,4-trimethylpentane + 1-propanol at 298.15 K and 303.15 K and calculated the excess molar volumes of the mixtures. Nath and Pandey measured the excess molar volumes of 2,2,4-trimethylpentane + 1-heptanol at 293.15 K and 298.15 K by means of the dilatometric technique.…”

Surface Tension of Binary Mixtures of 2,2,4-Trimethylpentane +1-Alkanols from 298.15 to 323.15 K

“…For 2,2,4-trimethylpentane + ethanol, Chen et al , published the densities, viscosities, and refractive indices from 288.15 to 318.15K. Faneite et al measured the densities of 2,2,4-trimethylpentane + 1-propanol and 1-pentanol at 298.15 K over the whole composition range. Densities and excess molar volumes for 2,2,4-trimethylpentane with 1-propanol were reported at 298.15 and 303.15 K by Hwang et al , The excess molar volumes of 2,2,4-trimethylpentane with 1-heptanol at 293.15 and 298.15 K were reported by Nath et al , The densities, viscosities, and excess mole volumes of 2,2,4-trimethylpentane + 1-propanol, 1-pentanol, 1-hexanol, or 1-heptanol from 298.15 to 323.15K were measured by Wang et al Unfortunately, a survey from the literature shows that there are no reports on the measurements of surface tension for 2,2,4-trimethylpentane + 1-alkanols binary systems.…”
