DIPOLAR ASSOCIATION IN BINARY-SYSTEM - MIBK IN CARBOXYLIC-ACIDS

The dielectric constant (epsilon) of the binary mixtures of MIBK with some carboxylic acids viz. acetic acid, propanoic acid and butyric aci d is measured at 303.16 K at 455 kHz. The experimental data are used t o compute the excess dielectric constant (Delta epsilon), mutual corre lation factor (g(ab)); excess molar polarization (Delta P) and excess free energy of mixing (Delta G(ab)) in these mixtures.
