Cibulka correlation for ternary excess/deviation properties of C2mim EtSO4 (x1) + acetic or propionic acid (x2) + acetonitrile (x3) systems at different temperatures
(Elsevier, 2017)In this perspective, the main intention is to reveal the possible intra and inter molecular interactions between ternary ionic liquid systems. The excess molar volume (VE123), isentropic compressibility (ks) and deviation ... -
Coal particle and bed physical transformational behaviour after thermochemical conversion in a fixed bed
(Elsevier, 2016)This paper examines the physical transformational behaviour that coal particles and the bed structure undergo in a fixed bed reactor. The transient overfeed configuration is used with feed gas entering from the bottom of ... -
Density and speed of sound measurements of imidazolium-based ionic liquids with acetonitrile at various temperatures
(2014)In the present study, the interactions between acetonitrile and imidazolium-based ionic liquids (ILs) were discussed in terms of density (ρ) and speed of sound (u) measurements. The ILs used in this study were 1-ethyl-3- ... -
Density and speed of sound of 1-ethyl-3-methylimidazolium ethyl sulphate with acetic or propionic acid at different temperatures
(Elsevier, 2014)In this work, new density, ρ, and speed of sound, u, were measured for IL, acetic acid, propionic acid, and their binary systems {IL (x1) + acetic or propionic acid (x2)} at 293.15, 298.15, 303.15, 308.15 and 313.15 K under ... -
Effect of temperature on density, sound velocity, and their derived properties for the binary systems glycerol with water or alcohols
(Elsevier, 2017)Densities and sound velocities of three binary systems containing glycerol + (water, methanol, or ethanol) have been measured over the entire composition range at temperatures ranging from (283.15 to 313.15) K in 10 K ... -
Influence of alkyl group on interactions between carboxylic acid and acetonitrile at different temperatures
(Elsevier, 2016)In this paper, the influence of alkyl group as well as temperature on interactions between carboxylic acid and acetonitrile were examined using thermodynamics technique. The carboxylic acid used in this study was acetic ... -
Intermolecular interactions between 2-methyl-2-butanol and petroleum ether at different temperatures: density, viscosity and refractive index measurements
(Elsevier, 2016)Experimental data of densities, dynamic viscosities, at 293.15, and 303.15 K as well as refractive indices at 293.15, 303.15, 313.15 and 323.15 K were measured for the binary systems of 2-methyl-2-butanol and petroleum ... -
Physicochemical properties of N-Butyl-N-methyl-2-oxopyrrolidonium bromide and its binary mixtures with water or methanol
(American Chemical Society, 2016)Novel N-butyl-N-methyl-2-oxopyrrolidonium bromide ([BMpyr]+[Br]?) ionic liquid was synthesized and characterized by different techniques such as NMR (1H and 13C), FTIR, and HPLC. The measurements of thermophysical properties ... -
