Determination and correlation of the solubility of four Brønsted-acidic ionic liquids based on benzothiazolium cations in six alcohols

Solubility Determination and Thermodynamic Modeling of Amitriptyline Hydrochloride in 13 Pure Solvents at Temperatures of 283.15–323.15 K

“…As shown in Figure 4, this character is very pronounced at the higher temperature range. The so-called "temperature-sensitive" property 19 is of vital practical significance for the separation of AMT and the recycle of the solvents.…”

“…M G H S , , and = (19) where Δ mix M is the thermodynamic mixing property; Δ mix M id is the thermodynamic mixing property of an ideal solution system.M E is the excess property of the solution system, which can be evaluated in terms of the regressed parameters of the Wilson model by eqs 20−22. The activity coefficient (γ 1 ∞ ) and the reduced excess enthalpy (H 1 E, ∞ ) at infinitesimal concentration can be evaluated from eqs 23 and 24.…”

Phase behavior of novel functional tropine ionic liquids in binary solvent mixture (water + ethanol): A synergistic effect promoting solubility

“…In addition, the sapphire method was used to measure the change of heat capacity at melting temperature [21], and molar volume of ILs was calculated by the group contribution method [22]. Table 3 and called "temperature-sensitive" property [7,23], which has the vital practical significance to the separation and re-usage of tropine-type ILs from its solution.…”

“…Ionic liquids (ILs) with their special properties are driving new researches and applications in many fields, such as good multi-function solvents applied in extractive distillation process [1], new kind of catalyst [2,3] and application in the extraction of natural products [4,5]. Thus various new types of ILs were synthesized in the past decades, such as isoquinoline-based [6], benzothiazolium-based [7], pyridine-based [8] and so on. A large amount of applications in various of fields have been investigated and developed, while the physicochemiacal property of IL is always essential and can lay the foundation for the application of ILs.…”

“…Any detailed knowledge of important binary and ternary mixtures behaviour, which is paramount for the design of any technological processes, is of course even significance. For example, some researches focused on the solubility of imidazolium and benzothiazolium ILs in aqueous and alcohol solutions [9][10][11], and it has been found that benzothiazolium-based ILs have temperature-sensitive property in alcohols [7].…”
