The Ultrasonic velocity studies on intermolecular interactions of binary liquid mixtures of Ethylene Glycols (EG) + n-butylamine (NBA), + sec-butylamine (SBA) + tert-butylamine (TBA), + n-hexylamine (NHA), + n-octylamine (NOA) and + cyclohexylamine (CHA) have been measured at 308.15K. From the experimental results the excess molar volume (VE), excess viscosities (ηE), and excess molar Gibbs free energy of activation of viscous flow (G*E) have been computed as a function of composition. The parameter d1 of the Grunberg and Nissan expression has been computed. The values of VE are negative whereas the values of ηE, G*E and d1 are positive. Deviations from the ideal behavior are discussed from the point of view of the molecular interactions present between the unlike molecules. The strength of these interactions is related with the chain length of the amines. The results are discussed in terms of the theories of non-electrolyte solutions.
