ABSTRACT

Herein, physico-chemical functions were obtained using density ( ) and speed of sound ( u ) data of tributylamine (TBA) + alkyl acetates (C1-C5) mixtures at pressure of 760 mmHg and at five different temperatures (293.15-313.15) K. Anton Paar DSA 5000M was used to determine the values of density ( ) and speeds of sound ( u ) of the pure components and respective binary mixtures. The variation of excess molar isentropic compressibility compressibility ( K SE, m ), E excess speed of sound ( u E ), partial molar volume ( V i ), excess partial molar volume ( V i ) and apparent molar volume, ( V ,m ) with composition were examined in terms of intermolecular interactions which is also supported by FT-IR studies. It has been found that the functions obtained from density and speed of sound data ( VmE and K SE,m ) are positive at all concentration and at (293.15-313.15) K, which shows the presence of weak intermolecular interactions (dipole-dipole type). The results obtained for VmE experimentally and theoretically (PFP theory) were correlated with each other.
