Viscosity of Alkanol + Alkane Mixtures at Moderately High Pressures

High-Pressure Viscosity Measurements for the Ethanol + Toluene Binary System

“…Figure 3 shows the deviations obtained for ethanol viscosities measured in this work as well as the interpolated literature values [6,[22][23][24][25], when these viscosity data are compared with the average value obtained by fitting all viscosity values at the corresponding isobar as a function of temperature. This figure shows a very good agreement between the ethanol viscosities of this work and those reported in the literature [6,[22][23][24][25].…”

“…The measured ethanol viscosities have been compared with literature values [6,[22][23][24][25], which are available up to 60 MPa in the temperature range from 293.15 to 373.15 K. The literature data have been interpolated in order to obtain values corresponding to the pressures considered in this experimental work. Figure 3 shows the deviations obtained for ethanol viscosities measured in this work as well as the interpolated literature values [6,[22][23][24][25], when these viscosity data are compared with the average value obtained by fitting all viscosity values at the corresponding isobar as a function of temperature.…”

“…2-5. In order to study the behavior of ethanol + petroleum fluids under various operating conditions, experimental property measurements of simplified mixtures can provide valuable information about their behavior both from a fundamental as well as an applied point of view. Although the viscosity is an important fluid property required in various engineering disciplines, only a few experimental viscosity studies under pressure have previously been performed on systems involving alcohols and hydrocarbons [6,7].…”

Comparative experimental and modeling studies of the viscosity behavior of ethanol+C7 hydrocarbon mixtures versus pressure and temperature

“…Although the viscosity is an important fluid property, which is required in a wide range of engineering disciplines, only a few experimental studies have previously been performed for alcohol + hydrocarbon systems under pressure [2,3]. Due to the lack of high-pressure viscosity measurements, an extensive experimental study has been initiated on binary systems composed of ethanol and C 7 hydrocarbons in order to provide experimental data and to study the influence on the viscosity behavior related to different chemical families.…”
