“…Mixtures of those solvents with RTILs have been often studied for imidazolium [52,53] and recently also for phosphonium ILs [3]. is not so sharp when it is compared with those shown by other liquids, such as water [54], dichloromethane [55], ethanol [56], and nhexane [57]. However for n-dodecane the variation is weak [58] similar to that found for the ILs.…”

“…To make the present results easily usable for engineering and design purposes, the modified Tammann–Tait equation was applied to correlate the experimental high-pressure density data and also to calculate various derived properties. It is one of the simplest empirical equations and is widely used ,− as a common method to correlate liquid density data over a broad pressure and temperature range: where ρ ref denotes density of the sample at reference pressure, p ref =0.1 MPa, and it depends on temperature, as well as B ( T ), while C is a temperature-independent parameter. ρ ref and B ( T ) could be expressed as a function of temperature by considering a second-order polynomial form: and a i , b i , and C are adjustable parameters.…”

Densities, speeds of sound, and refractive indices of methyl laurate, ethyl laurate, ethyl myristate, and ethyl oleate in the temperature range 288.15−343.15 K and viscosities from 288.15 to 373.15 K were measured at atmospheric pressure. The measured properties were in good agreement with several available literature data, finding an overall absolute average percentage deviation (AAD) of 0.04%, 0.07%, 3%, and 0.1% for density, speed of sound, viscosity, and refractive index, respectively. The densities of mentioned esters were also measured along 15 isotherms from 293.15 to 413.15 K and at pressures up to 60 MPa using an Anton Paar DMA HP densimeter. Based on the literature data selected for comparison, in the studied ranges of temperature and pressure, the AADs of high-pressure densities were 0.08% for methyl laurate, 0.06% for ethyl laurate, and 0.05% for ethyl myristate. The obtained density values were correlated through the modified Tammann−Tait equation with an AAD lower than 0.009% for all the studied esters. The adjusted parameters were used to calculate the isothermal compressibility, isobaric thermal expansivity, internal pressure, and difference in isobaric and isochoric heat capacities. It was found that methyl laurate has higher density, speed of sound, and refractive index than ethyl laurate of the same fatty acid, while viscosities for the ethyl are slightly higher than those of the methyl laurate. The values of the isothermal compressibility and the isobaric thermal expansivity for ethyl laurate are slightly higher than those for methyl.

“…The determination of the liquid density of neat C x mimTfO (x = 2, 4, 6) as a function of temperature T was carried out applying a vibrating tube densimeter (DMA 5000, Anton Paar GmbH, Graz, Austria) at ambient pressure conditions. Reference density data of water 61 within a temperature range of 293.15 K ≤ T ≤ 363.15 K and reference density data of cyclohexane 62 and dichloromethane 63 within a temperature range of 293.15 K ≤ T ≤ 308.15 K and 293.15 K ≤ T ≤ 348.15 K, respectively, were used for calibration at ambient pressure. The estimated uncertainty of a single density measurement is u(ρ) = 4.6 × 10 −4 g•cm −3 .…”

Vapor Liquid Equilibria of 1-Ethyl-3-methylimidazolium Triflate (C₂mimTfO) and n-Alkyl Alcohol Mixtures

The isobaric vapor liquid equilibria (VLE) of different binary mixtures of the ionic liquid (IL) 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (C2mimTfO) with the n-alkyl alcohols, methanol, ethanol, propan-1-ol, and butan-1-ol, are studied at the pressures of p = 500, 700, and 1000 mbar, covering a composition range 0.25–0.35 ≤ x(solvent) ≤ 1.0. Complementarily, the experimental results are compared with calculations by the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state (EoS). For deriving suitable PC-SAFT parameters, experimental liquid densities were determined for the neat IL C2mimTfO and its longer homologues, 1-butyl-3-methylimidazolium trifluoromethanesulfonate (C4mimTfO) and 1-hexyl-3-methylimidazolium trifluoromethanesulfonate (C6mimTfO), in a temperature range of 288.15 K ≤ T ≤ 363.15 K (C2mimTfO) and 293.15 K ≤ T ≤ 363.15 K (C4mimTfO and C6mimTfO), respectively. The PC-SAFT EoS is found to be suitable for describing the VLEs under study with good accuracy (AARDVLE ≤ 0.4%).
