Ultrasonic investigation of effective Debye temperature in multi-component liquid systems at 298.15 K

Abstract

Assuming the quasi-crystalline model for the multi-component liquid systems, the effective Debye temperature has been investigated from the density and sound velocity measurements of three ternary and three quaternary liquid systems containing n-alkanes over the entire range of mole fractions at 298.15 K. The results obtained have been interpreted in terms of intermolecular interactions and modifications of the internal structure of the mixtures.
