Influence of temperature on thermodynamics of protic ionic liquid 2-hydroxy diethylammonium lactate (2-HDEAL) + short hydroxylic solvents

摘要: Abstract In this work, we synthesized the protic ionic liquid 2-hydroxy diethylammonium lactate (2-HDEAL), volumetric and acoustic behavior into different hydroxilic media (water, methanol ethanol) at range of temperature 288.15–323.15 K atmospheric pressure being studied. The corresponding apparent molar volume isentropic compressibility values have been evaluated from experimental data fitted to a dependent Redlich–Mayer equation. Derived properties such as isobaric expansibility isothermal coefficient excess enthalpy other acoustical parameters were computed due their importance in study specific molecular interactions environment. new used test prediction capability models (Mchaweh–Nasrifar–Moshfeghian (MNM) model, modified Heller equation (MHE) Collision Factor Theory (CFT)). obtained results indicate that water are weaker than studied alcoholic solutions, accordance with previous results. volumes negative throughout composition for all mixtures any condition. observed inverse dependence on aqueous or mixtures, points out special trend packing solvents its strong steric hindrance aliphatic residues anions cations.
