“…Buchowski and co-workers originally proposed the λh model, , and this model is widely used to correlate the solid–liquid equilibrium. The relationship between the experimental solubility and the temperature is shown as follows: where T is the absolute temperature (K); x represents the experimental value of mole fraction of florfenicol in the pure or binary solvents at the system temperature, which was calculated with eqs or ; T m is the melting point of florfenicol, according to the DSC curve, the onset temperature T m = 425.15 K; and λ and h are the empirical constants, they were obtained from fitting the experimental solubility data with eq .…”

The solubility of florfenicol form A in eight pure organic solvents (propionic acid, ethanol, 1-propanol, 1-butanol, 2-propanol, 2-methyl-1-propanol, 3-methyl-1-butanol, and 2-ethyl-1-hexanol) and three binary solvents (dimethyl sulfoxide + ethanol, dimethyl sulfoxide + 1-propanol, and dimethyl sulfoxide + 1-butanol) was measured by a laser dynamic method at temperature from 283.15 to 323.15 K. The experimental results show that the mole fraction solubility of florfenicol in the pure solvents decreased according to the following order: ethanolThe experimental results show that the mole fraction solubility of florfenicol form A in the binary solvents increased with the increase of temperature and dimethyl sulfoxide mass fraction. The experimental solubility data were well correlated with the four thermodynamic models: modified Apelblat equation, λh equation, NRTL model equation, and Wilson model equation. The modified Apelblat model equation was regarded as the best one to fit the experimental values in the pure solvents.

Cilostazol is a neutral molecule with poor solubility. In this work, the solubility data of cilostazol in 10 pure and 1,4-dioxane + ethanol binary solvents was measured using the isothermal saturation method within the temperature range from 273.15 to 313.15 K at atmospheric pressure. In the 10 pure solvents, the results indicated that the maximum and minimum solubility of cilostazol appeared in 1,4-dioxane and isopropanol, respectively. The sequence of solubility was 1,4-dioxane > 2-butanone > acetone > 1-butanol > acetonitrile > methanol > n-propanol > ethanol > ethyl acetate > isopropanol. In a mixture of 1,4-dioxane + ethanol, it first increased and then decreased with increasing mass fraction of 1,4-dioxane in 1,4-dioxane + ethanol mixtures at all selected temperatures. The dissolution process of cilostazol was analyzed by the solvent properties. Moreover, the solubility data of cilostazol in the 10 pure solvents was correlated with the modified Apelblat and λh equations. The result in binary mixture at various temperatures was evaluated by the Jouyban–Acree model. In a pure solvent, the RAD values between the experimental and calculated data with modified Apelblat and λh equations were all no larger than 3.57 × 10–2 and 11.40 × 10–2, respectively. In 1,4-dioxane + ethanol binary mixtures, the RAD data of the Jouyban–Acree model was 6.22 × 10–2. The study of the dissolution process for cilostazol is an important aspect of its purification and recrystallization.

“…This affects the physicochemical properties of the micellar solutions, e.g., cmc, the average aggregation number ( N agg ), and the degree of counter-ion dissociation (α mic ). This problem was mentioned explicitly by some authors (precaution was taken to suppress its effect) [ 12 ] but not others [ 13 ], even when the ILBSs were heated with methanol at 85 ° C for 8 h [ 14 ]. A literature survey using the search terms (HF, pH and hydrolysis) for the above-mentioned ILBSs showed that the time elapsed between preparing the ILBS solutions and the measurements/applications was not mentioned [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ].…”

Ionic Liquid-Based Surfactants: Recent Advances in Their Syntheses, Solution Properties, and Applications

et al. 2021

The impetus for the expanding interest in ionic liquids (ILs) is their favorable properties and important applications. Ionic liquid-based surfactants (ILBSs) carry long-chain hydrophobic tails. Two or more molecules of ILBSs can be joined by covalent bonds leading, e.g., to gemini compounds (GILBSs). This review article focuses on aspects of the chemistry and applications of ILBSs and GILBSs, especially in the last ten years. Data on their adsorption at the interface and micelle formation are relevant for the applications of these surfactants. Therefore, we collected data for 152 ILBSs and 11 biamphiphilic compounds. The head ions of ILBSs are usually heterocyclic (imidazolium, pyridinium, pyrrolidinium, etc.). Most of these head-ions are also present in the reported 53 GILBSs. Where possible, we correlate the adsorption/micellar properties of the surfactants with their molecular structures, in particular, the number of carbon atoms present in the hydrocarbon “tail”. The use of ILBSs as templates for the fabrication of mesoporous nanoparticles enables better control of particle porosity and size, hence increasing their usefulness. ILs and ILBSs form thermodynamically stable water/oil and oil/water microemulsions. These were employed as templates for (radical) polymerization reactions, where the monomer is the “oil” component. The formed polymer nanoparticles can be further stabilized against aggregation by using a functionalized ILBS that is co-polymerized with the monomers. In addition to updating the literature on the subject, we hope that this review highlights the versatility and hence the potential applications of these classes of surfactants in several fields, including synthesis, catalysis, polymers, decontamination, and drug delivery.
