Effect of tri-potassium phosphate on volumetric, acoustic, and transport behaviour of aqueous solutions of 1-ethyl-3-methylimidazolium bromide at T=(298.15 to 318.15)K

Evaluation of the impact of phosphate salts on the formation of ionic-liquid-based aqueous biphasic systems

“…In addition, the phosphatebased inorganic salts were selected because they are important ions in biological systems [35]. K 3 PO 4 is indeed the most studied salt as a salting-out species [3,7,13,19,31,[36][37][38][39][40][41][42][43] followed by KH 2 PO 4 and KH 2 PO 4 /K 2 HPO 4 mixtures which are also frequently used at the biotechnological field [19,33,43,45,46].…”

Solvation properties of acetaminophen in aqueous ionic liquid, 1-hexyl-3-methylimidazolium bromide, solutions at different temperatures

“…Hence, they are finding increasing uses in many areas of 54 technology and science, such as in nanoscience [6-8], synthesis [9,10], 55 catalysis [11 -13], separations [14,15], and as liquid electrolytes for elec- 56 trochemical processes [16,17]. 57 In the past few years, ILs have also gained interest for use in several 58 pharmaceutical applications such as solubilization of poorly soluble 59 drugs, synthesize active pharmaceutical ingredients (APIs) with modi- 60 fied solubility, increased their thermal stability, as solvent in the synthe- were obtained from the experimentally measured densities using the 171 following equation: to Masson ' s equation [48]: …”

Apparent molar volumes, apparent isentropic compressibilities, and viscosity B-coefficients of 1-ethyl-3-methylimidazolium bromide in aqueous di-potassium hydrogen phosphate and potassium di-hydrogen phosphate solutions at T=(298.15, 303.15, 308.15, 313.15, and 318.15)K

“…In our previous work [13] we studied the effect of tri potassium phosphate on the volumetric, acoustic, and transport behavior of aqueous solutions of 1-ethyl-3-methylimidazolium bromide (EmimBr) at T = (298.15 to 318.15) K. In this work, we report studies on the interaction of (EmimBr) with di-potassium hydrogen phosphate (K 2 HPO 4 ) and potassium di-hydrogen phosphate (KH 2 PO 4 ) by densimetry and viscometry at T = (298.15 to 318.15) K, for which such information is not available in the literature. There is only a few density data for dilute aqueous (EmimBr) solutions [14] and a few experimental viscosity data has been reported at T = 298.15 K [15] for aqueous (EmimBr) solutions.…”
