In an analytical way effective Debye temperature computations of functional materials are extended to organic liquid mixtures using ultrasonic velocity and density measurements. Thermal properties of organic liquid mixture containing Aniline + Toluene, Aniline + o-Xylene and Aniline + Mesitylene over different mole fractions have been explained using Debye temperature variations and they are scrutinized to bring out the molecular association due to thermal energy changes of binary liquid mixtures. The results including computation of Debye temperatures using standard formula, ideal mixture relation and modified Lorentz-Bertholet combination mixing rule and their deviations are used to explain thermal energy changes of component molecules in liquid mixtures and their association.
