Volumetric and Viscometric Properties of Binary Mixtures of Aliphatic Alcohols (C₁−C₄) with Nitroethane from 293.15 K to 313.15 K

Abstract

Densities and viscosities were measured for the binary mixtures of methanol, ethanol, propan-1-ol, propan-2-ol, butan-2-ol, and 2-methylpropan-2-ol with nitroethane at temperatures from 293.15 K to 313.15 K and atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were measured with an automatic Ubbelohde capillary viscometer. The estimated uncertainties are less than (0.05% for density and (0.7% for viscosity. Excess volumes and viscosity deviations as a function of mole fraction average were derived, and the computed results were fitted to the Redlich-Kister equation. Furthermore, McAllister's three-body-interaction model is used to correlate the binary kinematic viscosities and the binary densities.

Densities and Viscosities for Binary Liquid Mixtures of Biodiesel + 1-Butanol, + Isobutyl Alcohol, or + 2-Butanol from 293.15 to 333.15 K at 0.1 MPa

“…We have measured the viscosity of biodiesel + (1-butanol, isobutyl alcohol, and 2-butanol) from 293.15 to 333.15 K at atmospheric pressure. Our viscosity measurements for the pure alcohols agree with the literature ,,− data within an AAPD of 1.1% for 1-butanol and 2-butanol and 1.6% for isobutyl alcohol, respectively. A comparison is shown in Table .…”

Excess Volumes, Densities, Speeds of Sound, and Viscosities for the Binary Systems of 1-Octanol with Hexadecane and Squalane at (298.15, 303.15 and 308.15) K

“…The estimated purities determined by gas chromatographic analysis were better than 99.5 mol % for all the liquid samples. Furthermore, the purities of the liquids were checked by comparing densities, ρ, viscosities, η, and speeds of sound, u, with corresponding literature values [11,14,[20][21][22][23][24][25][26][27][28][29][30], as reported in Table 1.…”
