“…In this regard, it is necessary to study the properties of alcohol with FAME or FAEE binary mixtures. In our laboratory, we have carried out a series of investigations on the density and viscosity of alcohol/FAME or alcohol/FAEE mixtures at atmospheric pressure. − However, there is still a gap in the density and viscosity of these mixtures at high pressures. Hence, in this work, the high-pressure density and viscosity of the binary mixtures of 1-propanol and ethyl caprate (one of the FAME) were measured for the first time.…”

The liquid densities and viscosities of ethyl caprate/1-propanol mixture were investigated at ethyl caprate molar fractions of 0.25, 0.50, and 0.75 in this work. The measurements were carried out using a vibrating-tube densimeter and a falling-cylinder viscometer, and the studied temperature range was from 293 to 363 K, and the pressure was up to 60 MPa for density and 30 MPa for viscosity. The Tait equation was used to correlate the experimental densities. In addition, for comparison purpose, the modified Andrade equation and the Vogel–Fulcher–Tammann (VFT) equation were used to correlate the viscosities. For the density and viscosity of the mixtures at different molar fractions, the average absolute relative deviations between experimental and calculated values are all less than 0.01 and 0.47%, respectively.

High-Temperature and High-Pressure PVT Measurements of the Binary n-Hexane + Methyl Octanoate Mixture near the Critical Point of the Pure Solvent (n-Hexane)

PρT and phase transition properties (P S ,ρ S ,T S ) of the dilute binary mixture of n-hexane + methyl octanoate (at a concentration of 0.057 mol fraction of methyl octanoate) have been studied using the constant-volume piezometer technique. The measurements were performed along 16 liquid, vapor, and nearcritical isochores between 32.38 and 615.57 kg•m −3 over a temperature range from 291 to 633 K at pressures up to 16 MPa. Measurements were concentrated in the immediate vicinity of the critical point of pure n-hexane and liquid−gas phase transition points (bubble and dew point curve) in order to study the effect of critical fluctuations in pure n-hexane on the thermodynamic properties of the dilute mixture and to closely observe the phase transition changes and precise measurements of the (P S ,ρ S ,T S ) and critical point (P C ,ρ C ,T C ) data. The measured critical property data for the mixture were used to study the isomorphic critical behavior of strongly (isothermal compressibility K TX and isobaric heat capacity C PX ) and weakly (isochoric heat capacity C VX ) singular properties along the critical isochore and the critical isotherm. The measured PρT data were also used to estimate the values of physical meaning (theoretically important) parameters, namely, characteristic reduced temperature ( , ) 1 2 and density differences ( , ) 1 2 of the mixture. Based on the measured critical property data, the value of the Krichevskii parameter K kr has been estimated, which defines the structural (N exc )and thermodynamic (V H C , , 2 2 2 P ) properties of the dilute mixture near the critical point of the pure solvent (n-hexane).

“…Therefore, it is imperative to study fuels’ thermophysical properties comprehensively. Lately, many investigators shifted their research interest to pure FAMEs or FAEEs’ thermophysical properties or mixtures contained in them. ,,− Nevertheless, no sufficient reported literature on biodiesel components mixtures’ thermal conductivity has been found. As a vital thermophysical property, thermal conductivity is required for the thermal design and optimization of a diesel engine. , In this work, the thermal conductivity of three binary mixtures was measured in the temperature between 292 and 362 K at atmospheric pressure.…”

Experimental Research on the Thermal Conductivity of Binary Mixtures with a Biodiesel Compound Ethyl Laurate + Three Alcohols (1-Propanol, 1-Butanol, and 1-Pentanol)

Biodiesel is recognized as a powerful substitute for diesel fuel. The alcohol can be blended with diesel or biodiesel for certain property improvements. In this research, the liquid thermal conductivity of binary mixtures containing ethyl laurate, typically the important biodiesel component + three alcohols (1-propanol, 1-butanol, and 1-pentanol), was measured in the temperature range between 292 and 362 K at atmospheric pressure. It is estimated that the experimental results’ overall standard uncertainty was no more than 2%; the repeatability was less than ±0.5%. From the experimental data of three binary mixtures, three correlations have been fitted and optimized as they are available in calculating the mixtures’ liquid thermal conductivity.
