Excess Volume and Isentropic Compressibility of Binary Mixtures of Diethanolamine or Triethanolamine with Aniline from (303.15 to 318.15) K

In the present work, density of two binary mixtures of Diethanolamine (DEA) andTriethanolamine (TEA) with Aniline are measured with an Anton Paar DSA 5000 vibrating tubedensimeter and sound analyzer. The experiments are carried out at atmospheric pressure and303.15 to 318.15 K. Using the density and velocity of sound data, the several physical andthermodynamic properties such as excess molar volumes ( ) ,Isentropic Compressibility ( )and isentropic compressibility deviation ( for these binary mixtures [1]. The excess molarvolumes for the two aniline systems involving DEA and TEA are positive and this suggest thebreaking of hydrogen-bonds between molecules involved in the blend [2].
