ABSTRACT

This paper presents the experimentally determined values of density ( ), viscosity ( ), speeds of sound (u) and surface tension ( ) for binary systems of tert-amyl methyl ether (TAME) with n-hexane and mxylene at different temperatures (298.15, 308.15, 318.15, 323.15 and 328.15 K). Various excess/deviation properties such as molar volume ( ), isentropic compressibility ( ), speed of sound ( ), deviation in viscosity (Aln ), isobaric thermal expansion coefficient ( ) and surface tension ( ) have been calculated using the experimental data. The tendency of these properties have been analyzed to determine the type of specific molecular interactions as well as mixing behavior of solutions. The qualitative analysis of these parameters have revealed the presence of strong and weak specific interactions in TAME with m-xylene and TAME with n-hexane systems respectively.
