DIELECTRIC STUDIES OF HYDROGEN-BONDED BINARY-SYSTEMS - KETONE PLUS NITRILE

The dielectric properties of the hydrogen bonded binary systems of pol ar liquids containing ketone and nitrile functional groups are studied . The system are: (A) acetone + acetonitrile, (B) acetone + acrylonitr ile (C) 2 butanone + acetonitrile and (D) 2 butanone + acrylonitrile s ystems. The dielectric dispersion of the pure binary systems and their dilute solutions in a non-polar solvent namely benzene are studied. D ipole moments of the binary systems are calculated from the dielectric data using Guggenhiem's and Higasi's methods. The average relaxation time in the pure and dilute solutions is calculated from the respectiv e Cole-Cole plots. The dipole moment increment in the binary system ov er the sum of the pure values shows the absence of an ionic component to the binary conformer.
