Evaluation of sound velocity in binary systems of anisole with some aromatic compounds by different methods

Abstract

The sound velocity in binary liquid mixture of anisole with aniline, benzonitrile, nitrobenzene and <i>o</i>-chlorophenol has been evaluated using Nomoto's relation, ideal mixing relation, Jacobson's free length theory and Schaff's collision factor theory. The agreement between theoretical and experimental values is quite satisfactory. Non-ideality in the liquid mixtures has been expressed in terms of <em>U</em><img src='http://www.niscair.res.in/jinfo/equation81.gif' border=0>/<em>U</em><img src='http://www.niscair.res.in/jinfo/equation82.gif' border=0>, where <em>U</em>_exp and <em>U</em>_im refer to the experimental and ideal mixture velocities respectively.
