“…The apparatus and procedures used for solubility and density measurement have been described earlier. − An excess amount of NaI was added to the binary solvents mixtures prepared by weight (Shimadzu, Auxzzo) with an uncertainty of ± 0.1 mg, in a specially designed 100 mL double jacketed flask. Water was circulated at constant temperature between the outer and inner walls of the flask.…”

“…However there is no data available for solubility of sodium iodide in water–methanol, water–ethanol, and water–propan-2-ol for the complete binary composition range at temperatures mentioned above. Therefore in continuation of our work , we have undertaken systematic measurements of solubility and densities of sodium iodide in water + methanol/ethanol/propanol-2-ol binary solvents over the entire composition range from 0 to 1 mass fraction of methanol, ethanol, and propan-2-ol at (298.15, 303.15, 308.15, and 313.15) K. The experimental data of solubility at constant temperature in pure and mixtures of solvents were fitted in a combined nearly ideal binary solvent (NIBS)–Redlic–Kister equation. Solubility of NaI depends on not only the temperature but also the composition of the solvent mixture.…”

Solubility of NaI in water, methanol, ethanol, propan-2-ol, and also in water + methanol, water + ethanol, and water + propan-2-ol binary mixtures have been experimentally measured using a gravimetric method at temperatures (298.15.303.15, 308.15, and 313.15) K. The combined NIBS (nearly ideal binary solvent)–Redlic–Kister equation is used to fit experimental solubility data at constant temperature. The densities of the saturated solutions are also reported in pure and binary solvent mixtures at temperatures mentioned above. Thermodynamic functions including ΔH soln 0, ΔG soln 0, and ΔS soln 0 of solution of NaI are obtained from the modified van’t Hoff equation. A comparison of the relative contributions by enthalpy (ζH) and entropy (ζTS) is made which indicated that the main contributor to the positive standard molar Gibbs energy of solution of NaI is the entropy for solution of NaI in water + methanol having x C 0 < 0.5 and for all other solutions it is enthalpy.

Density of water, methanol, ethanol and water+methanol, water+ethanol binary solvent in pure form were experimentally measured. In these same series of solvents 2-naphthol was added to make saturated solutions of 2-naphthol at equilibrium. These saturated supernatant solutions were collected to measured densities and molalities of 2-naphthol at (293.15 to 313.15) K for comparative studies and experimental data used to calculate the excess molar volumes (V E ), apparent molar volume (V Φ ). Redlich−Kister Equation was used to calculate excess molar volumes (V E ) to correlate with the experimental excess molar volumes (V E ) of binary solvent mixture. Regressed Parameters Ai obtained from Redlich−Kister Equation were used for calculation of partial excess molar volumes at infinite dilution (V̅ i E,∞). Molecular interaction was explain by using Gaussian 09W software, DFT/B3LYP 6-31(G)d as basic set.-73 -investigate. We have undertaken the measurements of densities of pure solvents, binary solvent mixtures and saturated solutions of 2-naphthol in water + methanol and water + ethanol binary solvents over the entire composition range from 0 to 1 mole fraction of methanol, ethanol. Apparatus and Procedure:-The apparatus and procedures used for density measurement have been described earlier in detail [13,14]. Briefly in this work; an excess amount of 2-naphthol was added to the binary solvents mixtures prepared by weight (Shimadzu, Auxzzo) with an uncertainty of ± 0.1 mg, in a specially designed 100 ml jacketed flask. Water was circulated at constant temperature between the outer and inner walls of the flask. The temperature of the circulating water was controlled by thermostat to within (± 0.1) K. The solution was continuously stirred using a magnetic stirrer for sufficient time (about 3hr) so that equilibrium is assured, no further solute dissolved, and the temperature of solution is same as that of circulating water; the stirrer was switched off and the solution was allowed to stand for 1hr. Then 5 ml of the supernatant liquid was withdrawn from the flask in a weighing bottle with the help of pipette which is hotter than the solution. Solutions were dried gravimetrically till constant weight of weighing bottle was reached. Molality of 2-naphthol was calculated by constant weights of solute. This flask solution was used to fill bicapillary pycnometer.Densities were determined using a 15 cm 3 bicapillary pycnometer as described earlier [15,16]. For calibration of pycnometer triply distilled and degassed water with a density of 0.99705 g·cm −3 at 298.15 K was used. The filled pycnometer (without air bubble) with experimental liquids was kept in a transparent walled thermostat maintained at constant temperature (± 0.1 K) for 10 to 15 min. to attain thermal equilibrium. The heights of the liquid levels in the two arms were measured with the help of a travelling microscope, which could read to 0.01 mm. The estimated standard uncertainty of the density measurements of the solvent and binary mixtures was 10 kg·m −3 . Resul...

“…This separation process has several advantages compared to traditional methods of crystallization including increased yields, operation at ambient temperature, high purity of the product, and fitness for systems where the temperature has little effect on the solubility (Taboada et al, 2005;Kao and Tu, 2009;Pawar et al, 2009Pawar et al, , 2010. The main quality of the solvent is its capacity to generate supersaturation in the aqueous dissolution of the salt (Berry et al, 1997).…”

The solubility, density, and refractive index data for 1,2-propanediol þ Cs 2 SO 4 þ H 2 O, ethylene glycol þ Cs 2 SO 4 þ H 2 O, and glycerin þ Cs 2 SO 4 þ H 2 O ternary systems were determined at 15 C, 25 C, and 35 C. In all cases, the solubility of Cs 2 SO 4 in aqueous solutions decreased significantly due to the presence of the polyhydric alcohol. The experimental density, refractive index, and solubility data of saturated solutions for these systems were correlated using polynomial equations. Furthermore, the refractive index and density of unsaturated ternary solutions were also determined and correlated with salt concentrations and proportions of polyhydric alcohol in these systems.
