摘要：

Densities and speeds of sound of L-glutamic acid and L-aspartic acid in aqueous and aqueous solution of 1-methylimidazolium chloride [mim][Cl] have been measured at T = (288.15, 298.15 and 308.15) K under atmospheric pressure. The apparent molar volumes (V-phi), apparent molar volume at infinite dilution (V-phi())0, apparent molar isentropic compression (K-phi,K-s) and the apparent molar isentropic compression at infinite dilution (K-phi,s(0)) have also been computed from density and speed of sound data. Furthermore, limiting apparent molar expansion, E phi(0), and hydration numbers, n(H) have been evaluated to support the conclusions obtained from the volumetric and acoustic studies. These parameters are helpful to study the structure nurturing, solvation behavior and various interactions present in the ternary solutions of (amino acid + [mim][Cl] + water). (C) 2019 Elsevier B.V.
