“…Similarly, the impact of concentration and temperature variations was significant and provides important clues to the sweetener's behavior in aqueous solution. The smaller is the apparent molar volume, as compared to the molecular volume, the stronger will be the solute-solvent interactions as is the case with the studied sweeteners [8,15]. As a whole, the apparent molar volume represents the intrinsic volume and volume due to ion interactions with the solvent.…”

“…The mixtures were prepared by mass and were kept in special airtight stopper glass bottles to avoid evaporation. The density, sound velocity data and experimental methods are fundamental to establish a systematic experimental program and to implement the most appropriate techniques to determine density and the sound velocity of the sweetener in aqueous solutions at varying concentrations and temperatures [1,[14][15][16][17]. The solutions were prepared on the molal concentration scale using an electronic digital balance (Sartorius CP224S, model SAR CP224S, USA) with an accuracy of ±0.01 mg. Aqueous solutions of SC were prepared in the range of about 0.04-0.90 molÁkg -1 .…”

Density (q) and sound velocity (u) measurements were carried for aqueous solutions of sodium cyclamate (SC) from 293.15 to 318.15 K. Apparent molar and specific volumes, isentropic apparent molar compressibility and hydration numbers were computed from the experimental measurements. Apparent molar volumes (U V ) of SC show negative deviations from the Debye-Hückel limiting law and the values obtained for U V at given temperatures and concentrations were used as a direct measure of the ion-ion and ionsolvent interactions. Interactions causing a sweet taste require a specific volume to stimulate receptor sites from water and possibly also in the biophase. Furthermore, the partial molar expansibility (U E°) , Hepler's constant (q 2 U V°/ qT 2 ) and thermal expansion coefficient have been estimated. This study will help to elucidate the structural interactions of SC with water and its taste in foods.

BACKGROUNDTo improve the quality of wastewater and thereby to meet the standards as per environmental production agency in US and UK. In the present work, Malachite green (MG) and Naphthol Green B (NGB) has been taken as model dyes in wastewater. Solvent extraction process was carried out using deep eutectic solvents (DESs) as an alternative solvent for organic and ionic liquids.RESULTSThe possible molecular interaction between DESs and selective dyes in water were analyzed and discussed in details using volumetric properties including excess molar volume , partial molar volume , excess partial molar volume , apparent molar volume , isobaric thermal expansion () and excess isobaric thermal expansion (αE). Further, the extraction of selective dyes was conducted and characterized in terms of extraction efficiency (η), effect of temperature on extraction efficiency, effect of shaking time on extraction efficiency, effect of concentration on extraction efficiency, effect of HBD on extraction efficiency, distribution coefficient (D). Finally, the thermodynamic extraction feasibility was analysed by means of Gibbs free energy , change in enthalpy , and change in entropy .CONCLUSIONThere is possible molecular interaction between hydrophilic DESs and NGB/MG in water at molecular level. 96% of extraction efficiency was obtained for NGB using hydrophobic DESs like {[TBAB][DA]} and {[TBAB][OA]} whereas {[TBAB][DA]} and {[TBAB][OA]} gave above 72% removal efficiency of MG. Finally the thermodynamic feasibility of extraction process was analyzed and discussed. © 2023 Society of Chemical Industry (SCI).
