Abstract:

Ultrasonic velocity and density values have been measured for the binary liquid mixtures   of N,N Dimethyl Acetamide as a common component with Diethylamine, Diethanolamine and Benzylamine at 303, 308, 313 and 318K over the entire composition range. Theoretical velocity values have been evaluated by various relations viz., Nomoto, Free Length Theory (FLT), Van deal and Vangeel  ideal mixing relation (IMR), Impedance Dependence Relation (IDR), and Junjie for three binary liquid mixtures. An attempt has been made to compare the merits of the relations and the relative applicability of these theories to the present systems have been checked and discussed. The results are explained in terms of intermolecular interactions occurring in these binary systems. The deviation in the variation of  U2exp / U2 imx  from unity has also been evaluated for explaining the non-ideality in the mixtures
