Popis: When high amplitude sound waves propagate through liquid mixtures, various non-linear phenomena can occur, and ultrasonic research in these systems can reveal important details about their structure and interaction. Thermoacoustical parameters have been calculated for a binary system containing 1,4-butanediol(1,4-BD) + o-cresol(OC) or m-cresol (MC) or p-cresol(PC) at varying concentrations and temperatures ranging from 303.15 to 318.15 K. These parameters have been used to calculate available volume by using two different approaches. The results of both methods are used to examine the existence and intensity of interactions between the molecules in the systems under study. Additionally, several methods have also been used to derive the non-linearity parameter, or B/A. The excess values of B/A have also been calculated. In order to determine whether molecular interactions exist, a comparison analysis was conducted.
