Effect of ionic liquid, 1-hexyl-3-methylimidazolium bromide on the volumetric, acoustic and viscometric behavior of aqueous sucrose solutions at different temperatures

Measurement and Modeling of Solubility of Galactose in Aqueous Ionic Liquids, 1-Butyl-3-Methyl Imidazolium Bromide, 1-Hexyl-3-Methyl Imidazolium Bromide and 1-Butyl-3-Methylimidazolium Chloride at T = (298.15 And 308.15) K

“…To achieve this goal, a systematic study of thermophysical properties is required. In this work, in continuation to our previous papers, [13][14][15][16][17][18][19][20] the solubility values of galactose in aqueous ionic liquids, 1-butyl-3-methyl imidazolium bromide, [BMIm]Br, 1-hexyl-3-methyl imidazolium bromide, [HMIm]Br and 1-butyl-3-methylimidazolium chloride [BMIm]Cl have been measured at different ionic liquid mole fractions at T = (298.15 and 308.15) K using the gravimetric method. To model the experimental solubility data of galactose in water and aqueous ionic liquid solutions, models such as Wilson, 21 NRTL, 22 modified NRTL, 23 NRF-NRTL 24 and UNIQUAC 25 were used.…”

Water Activity in Aqueous Solution of Sucrose in the Presence of Some Deep Eutectic Solvents

“…In this regard, the local composition models, e-NRTL, 36 UNIQUAC, 37 and Wilson, 38 were used for fitting the data, which have been successful for similar systems in the literature. 39,40 Detail of the long-range equations of the models are described in refs 41−44.…”

“…Here, we used several models to fit the vapor–liquid equilibrium data for the ternary systems (DESs + sucrose + H 2 O). In this regard, the local composition models, e -NRTL, UNIQUAC, and Wilson, were used for fitting the data, which have been successful for similar systems in the literature. , Detail of the long-range equations of the models are described in refs − .…”

Vapor–Liquid Equilibrium, Volumetric, and Compressibility Properties of 1-Propanol + Poly(ethylene glycol) Dimethyl Ether 250 and 500 Binary Mixtures

“…The apparatus was held in constant temperature batch for at least 120 h for equilibration at 298.15 K by using a temperature controller (Julabo, MB, Germany) with standard uncertainty of 0.1 K. To determine isopiestic equilibrium molalities, the masses of isopiestic flasks in equilibrium were prepared by an analytical balance (Shimadzu, 321-34553, Shimadzu Co., Japan) with a precision of ±1 × 10 −7 kg as described previously. 28,29 The density and speed of sound of the solutions at different temperatures were measured with the digital vibrating-tube analyzer (Anton Paar DSA 5000, Austria) at a frequency (approximately 3 MHz) that was proportional to the temperature of an apparatus, maintaining the temperature of the samples with an uncertainty of 0.005 K by using Peltier device built in the densimeter. Degassed double distilled water and dry air were used to calibrate the apparatus at 298.15 K. The density of a known molality of aqueous NaCl given by Pitzer et al 30 was used to test the apparatus.…”
