摘要：

Dielectric constant of binary mixtures of Di-isobutylketone (DIBK) with some carboxylic acid viz. acetic acid, propionic acid and butyric acid is measured at 303.16 K and 455 kHz. The data are used to compute the mutual correlation factor g(ab), excess molar polarization DeltaP and Gibb's free energy DeltaG of mixing to study the molecular interaction. The study reveals that interaction is maximum in DIBK + butyric acid system and micro heterogeneous beta-clusters with antiparallel orientation of dissimilar molecules predominate in it.
