Thermodynamic Properties of the Hexyl Alcohols. V. 2,2-Dimethylbutanol-1 and 2-Ethylbutanol-1

Viscosity behavior of associated liquids at lower temperatures and vapor pressures

“…Although repeat measurements at and upward, of all the materials considered in the present work; overlap temperatures have not been conducted, numerical differentiation (see below) showed that in no case was there any discontinuity between our two sets of data. For the hexanols, our lower temperature values supplement those of Hovorka et al (2)(3)(4) which were made at room temperature to respective boiling points, but it is only for 2-ethylbutan-1-ol that the two sets of data fail to "marry".…”

“…temperature data of Thomas and Meatyard (14, 15) and Hovorka et al (2)(3)(4), supplemented by data-mostly at room temperature only-taken from Pollock and Stevens (5), Timmermans (17), Raznjevic (6), or Shell Chemical Corp. (7). Further details are given in Table II.…”

Determination of Vapor Pressures and Vaporization Enthalpies of the Aliphatic Branched C5 and C6 Alcohols

“…Only calorimetrically measured enthalpies of vaporization at 298.15 K have been reported by Wadsö and McCurdy and Laidler . Hovorka and co-workers − made vapor−pressure measurements of a number C 6 alcohols. Vapor−pressure measurements were also reported by Thomas et al for several aliphatic C 5 and C 6 alcohols over a wide range of temperature.…”

Physical Properties of Biodiesel Blended with Hexanol Isomers at Different Temperatures: Surface Tension, Density, Viscosity, and Refractive Index

“…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.…”
