“…Surface tensions, densities, viscosities, and refractive indices of both pure components and biodiesel blends with 1-hexanol, 4-methyl-2-pentanol, and 2-ethyl-1-butanol have been measured from 288.15 to 338.15 K and at atmospheric pressure. Properties for pure alcohols have been compared with those reported in the literature. − Figures S1–S4 (Supporting Information) show the relative errors between our experimental values and literature data. Our results agree with the literature values within average absolute percentage deviations (AAPDs) of 1.171, 0.024, 0.737, and 0.061 % for the surface tension, density, viscosity, and refractive index, respectively.…”

In this work, surface tensions, densities, viscosities, and refractive indices of biodiesel +1-hexanol, 4-methyl-2-pentanol, and 2-ethyl-1-butanol have been measured from 288.15 to 338.15 K at 0.1 MPa throughout the whole composition range. Du Noüy ring tensiometer, vibrating tube densimeter, glass capillary viscosimeter, and Abbemat refractometer are used to measure the surface tensions, densities, viscosities, and refractive indices, respectively. Our experimental results for the pure alcohols agree with literature values within average absolute percentage deviations of 1.171, 0.024, 0.737, and 0.061 % for the surface tension, density, viscosity, and refractive index, respectively. Experimental densities and viscosities of some of our biodiesel mixtures satisfy the limits set by the diesel fuel standard (EN 590), becoming potential substitutes of conventional diesel. Kinematic viscosities show a minimum value at alcohol mass fractions between 0.4 and 0.9. Thermodynamic properties and derived properties have been correlated using different equations reported in the literature.

“…The experimental values of densities, viscosities, and refractive indices of the pure samples under different temperatures are compared with those from the references ,,− in Table . The absolute average relative deviations (AARD) are calculated according to the following equation, and the results indicate that the experimental values agree well with the literature data. where P is the measurement data of density, viscosity, or refractive index in this work, and P lit is the literature data.…”

Density, Viscosity, and Refractive Index for Binary Mixtures of Three Adamantane Derivatives with n-Nonane or n-Undecane at T = 293.15–343.15 K and Atmospheric Pressure

et al. 2020

Measurements on densities, viscosities, and refractive indices at atmospheric pressure for binary mixtures of 1,3-dimethyladamantane (1,3-DMA), 1,3,5-trimethyladamantane (1,3,5-TMA), and 1-ethyladamantane (1-EA) with n-nonane or n-undecane are carried out over the whole composition range at temperatures T = 293.15−343.15 K and atmospheric pressure. The excess molar volume (V m E ), deviation in viscosity (Δη), deviation in refractive index (Δn D ), and deviation in molar refraction (ΔR) for the six mixtures are calculated and then fitted to the Redlich−Kister polynomial. The V m E values are all negative over the entire range of mole fractions and decrease with increasing temperature for the six binary systems. The absolute values of Δη for the mixtures decrease obviously with increasing temperature. The Δn D values with the volume fraction for the six systems are all positive over the entire composition range. Density, viscosities, and refractive index of the six systems are correlated by the Jouyban−Acree model. The experimental results could be useful for the development of high-energy-density hydrocarbon fuels.

“…This apparatus has been tested before with measurements of densities for nonane and decane and their binary mixtures [11]. Additionally, to check the performance of the VTD the densities of the pure compounds were compared with literature values [12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Densities and Excess Molar Volumes of Alkane (Heptane, Octane, Nonane, or Decane) + Thiophene from T=293.15 to 313.15 K

et al. 2012

View full text Add to dashboard Cite

Densities of four binary systems composed of an alkane (heptane, octane, nonane, or decane) and thiophene were measured at temperatures from 293.15 to 313.15 K at atmospheric pressure (0.7 atm). Measurements were made covering the full range of compositions for all systems studied and for the pure compounds by using a vibrating-tube densimeter (VTD). Excess molar volumes have been obtained from these experimental results and were fitted to a Redlich-Kister type expansion. The excess molar volumes exhibit positive deviations from ideal behavior for all of the binary systems studied here.
