“…In this regard, in the solution phase, Hepler developed a concept to establish a mode to study the solute–solvent interaction . The probability of making the structure-breaker or structure-maker interaction between the solute and the solvent also depends on the values of (δΦ E 0 /δ T) P /m 3 ·mol –1 ·K –2 according to the Hepler opinion false( δ normalΦ normalE 0 / δ T false) normalP = false( δ 2 normalΦ normalv 0 / δ T 2 false) normalP = 2 a 2 …”

Here, we have investigated some physicochemical parameters to understand the molecular interactions by means of density (ρ) measurement, measurement of viscosity (η), refractive index(n D ) measurement, and conductance and surface tension measurements between two significant aqueous ionic liquid solutions: benzyl trimethyl ammonium chloride (BTMAC) and benzyl triethyl ammonium chloride (BTEAC) in an aqueous Lmethionine (amino acid) solution. The apparent molar volume (Φ v ), coefficient of viscosity (B), and molar refraction (R M ) have been used to analyze the molecular interaction behavior associated in the solution at various concentrations and various temperatures. With the help of some important equations such as the Masson equation, the Jones−Doles equation, and the Lorentz−Lorenz equation, very significant parameters, namely, limiting apparent molar volumes (Φ v 0 ), coefficient of viscosity (B), and limiting molar refraction (R M 0 ), respectively, are obtained. These parameters along with specific conductance (κ) and surface tension (σ) are very much helpful to reveal the solute−solvent interactions by varying the concentration of solute molecules and temperature in the solution. Analyses of Δμ 1 0# , Δμ 2 0# , TΔS 2 0# , ΔH 2 0#, and thermodynamic data provide us valuable information about the interactions. We note that L-Met in 0.005 molality BTEAC ionic liquid at 308.15 K shows maximum solute−solvent interaction, while L-Met in 0.001 molality BTMAC aqueous solution of ionic liquid at 298.15 K shows the minimum one. Spectroscopic techniques such as Fourier transform infrared (FTIR), 1 H-NMR, and UV−vis also provide supportive information about the interactions between the ionic liquid and L-methionine in aqueous medium. Furthermore, adsorption energy, reduced density gradient (RDG), and molecular electrostatic potential (MESP) maps obtained by the application of density functional theory (DFT) have been used to determine the type of interactions, which are concordant with the experimental observations.

In order to comprehend the various properties of two amino acids (AAs), Lasparagine and L-glutamine, we have studied a number of physicochemical parameters, including density (ρ), absolute viscosity (η), refractive index (n D ), conductivity (σ), and surface tension (γ) in the aqueous solution of an ionic liquid (IL), benzyl-tributyl ammonium chloride (BTBAC), in (0.001, 0.003, and 0.005) molalities and five temperatures of 293.15, 298.15, 303.15, 308.15, and 313.15 K at atmospheric pressure of 0.1 MPa. Limiting apparent molar volumes (V φ 0 ) derived from the Masson equation, coefficient of viscosity (B) from the Jones−Doles equation, and limiting molar refraction (R M 0 ) from the Lorentz−Lorenz equation are applied to criticize the molecular interactions involving the AAs and the IL at different concentrations and temperatures. Transfer limiting apparent molar volume, V φ 0 tr , has been calculated to determine the solute−solvent interaction in an aqueous medium. The thermodynamic parameters such as Δμ 1 0⧧ , Δμ 2 0⧧ , ΔS 2 0⧧, and ΔH 2 0⧧ also suggest that the intermolecular interaction in the ground state is more significant compared to that in the transition state of two ternary systems. The UV−vis and 1 H nuclear magnetic resonance spectroscopy data also supported our experimental and theoretical observations. Optimization energy calculation obtained from the computational technique leads to the consequence of stability of the ternary system (IL + AA + H 2 O) at the molecular level.

L-Aspartic and L-Glutamic acid (two solute molecules) interact with an ionic liquid (Benzyl tri-methyl ammonium chloride) in aqueous medium. The interactions have been explained on the basis of some parameters (apparent molar volume, viscosity B-coefficient, molar refraction, specific conductance) at different temperatures and different concentrations from density, viscosity, refractive index, conductance measurements, respectively. Using Masson equation, the experimental slopes and the limiting apparent molar volumes are obtained which explain the solute-solute and solute-solvent interactions. Viscosity parameters, A and B obtained from Jones-Doles equation explained the solute-solute and solute-solvent interactions in the solution. Molar refraction has been calculated from the Lorentz-Lorenz equation. The specific conductance also explained the interaction properties.
