“…The physical property values of neat PEG are then obtained from extrapolations to zero water content .

This observation led us to expand our study to inspect the dependence of water content for PEG400 as well as for binary mixtures of triethylene glycol and hexaethylene glycol, where we inspect the entire composition range including a composition that results in an average molar mass near 200 g·mol –1 .…”

Polyethylene glycol (PEG) is increasingly used as an alternative green chemical solvent. New experimental measurements on density, viscosity, and self-diffusion coefficient are presented for PEG200, PEG400, and several binary mixtures of tri-and hexaethylene glycol covering a temperature range from 298.15 to 358.15 K. Because PEGs are polydisperse, the exact compositions of PEG200 from six different vendors are analytically determined and found to be comparable. Thus, only two of the most differing PEG200 samples are further examined. The effects of water as the most common impurity on densities, viscosities, and self-diffusion coefficients are inspected as well as the results of the "dry" samples obtained by extrapolation to zero water content. The obtained results are carefully compared to the available literature data. The temperature dependence of these physical properties is investigated and found to be linear for density, while viscosity and selfdiffusion coefficients follow the Arrhenius law. Attempts to calculate the properties of the binary mixtures and PEG200 samples from the mole fraction weighted average of the physical properties of the mixture components result in reasonable agreement. Agreement between calculated and measured molar volumes is within measurement uncertainty. Agreement of calculated and measured viscosities is mostly within a few percent but increases with decreasing temperature (largest viscosities) reaching values of up to 15%. Similarly, calculated and measured self-diffusion coefficients mostly agree within 20%, which is near the measurement uncertainty, but overestimates increase to 30% for the highest temperatures (largest self-diffusion coefficients).

“…Ionic liquids have attracted a lot of attention in the last few years in both the academic world and industry. − Some of their key properties include negligible vapor pressure, excellent thermal stability, high solubility, and nonflammability. Another important feature is that a series of physicochemical properties such as the density, viscosity, and electrical conductivity can be tuned by adjusting the nature of the constituting ions or by mixing with suitable/appropriate cosolvents. − One of the main characteristics of some ionic liquids is their high viscosity, which could be considered to be an advantage for applications such as lubricants , but could be a disadvantage for applications which involve pumping, mixing, stirring, and heat-transfer operations. , …”

New dynamic viscosity data are reported for binary mixtures of ionic liquid 1-hexyl-3-methylimidazolium tetrafluoroborate, [C 6 mim]-[BF 4 ], with polar aprotic solvents dimethyl sulfoxide (DMSO) and acetonitrile (ACN) over the whole composition range at experimental pressure p = 0.1 MPa. The temperature dependence of viscosity was studied in the T = (293.15 to 353.15) K temperature range. The viscosity data for binaries have been correlated with models based on Eyring's absolute rate theory with one, two, and three parameters and also with the classical equations of Grunberg−Nissan and McAllister. We also analyzed the capacity of the group contribution methods recently proposed by Zhao and Jacquemin for predicting the viscosity of binary mixtures with ILs. The results we obtained were promising, especially at lower temperatures, where the relative deviations, AAD%, were about 5 to 6%. The deviations in viscosity were calculated and correlated by a fourth-order Redlich−Kister type equation. The results were discussed in terms of interactions and interstitial accommodation between components in the binary mixtures.

“…Although, the ILs usage showed an excellent performance in the separation of sulfur‐containing compounds but the ILs production is expensive and this is not viable for a large‐scale application. [ 220–222 ] To overcome this issue, it is necessary to select some cheap IL which can be prepared easily and utilized for desulfurization of fuel oils. The new generation IL deep eutectic solvent (DES) is becoming popular now a days in the scientific community as it could provide the same properties with the traditional IL.…”

Nowadays, desulfurization of fuel oil has raised concern globally because of strict industrial and environmental legislations. Albeit hydrodesulfurization (HDS) has been extensively used in oil refineries to produce low sulfur oil (< 10 ppm) but not been proven as effective method for the removal of dibenzothiophene (DBT), benzothiophene (TH) and their derivatives. Subsequently, adsorptive desulfurization (ADS) and oxidative desulfurization (ODS) methods have been developed to achieve high removal efficiency. In the past decade, metal-organic frameworks (MOFs) and its composites as oxidative catalysts, as well as adsorbents, have attracted the researchers owing to high surface area, tunable properties, and reusable. The present review comprises use of MOFs and their composites for the removal of sulfur from fuel oil via ODS and ADS processes. Additionally, physicochemical properties of MOFs, mechanism, pros and cons of both process, regeneration, and future challenges have been discussed briefly. Moreover, current limitations and future prospective are also discussed.
