Effective Debye temperature of ionic liquids and their binary mixtures

Assuming the quasicrystalline structure to ionic liquids the effective Debye temperature of seven pure ionic liquids (H2O, DEAA, DEAS, TEAA, TEAS, TMAA, and TMAS.) has been calculated. Further, the model has been extended to six binary mixtures of (DEAA + H2O, DEAS + H2O, TEAA + H2O, TEAS + H2O, TMAA + H2O, and TMAS + H2O.). This is our first attempt in the study of thermal properties of pure ionic liquids and their binary mixtures. The concept of excess Debye temperature (theta(E)(D)) has been introduced and correlated with interactions in ionic liquid systems. The input data desired are density, sound speed, heat capacity and ratio of heat capacities (C-P/C-V). (C) 2021 Elsevier B.V. All rights reserved.

The effective Debye temperature of seven pure ionic liquids and their binary mixtures has been calculated in this first attempt to study the thermal properties. The concept of excess Debye temperature (θ(E)(D)) has been introduced and correlated with interactions in ionic liquid systems, using input data of density, sound speed, heat capacity, and ratio of heat capacities (C-P/C-V).
