Thermophysical approach to understand the nature of molecular interactions and structural factor between methyl isobutyl ketone and organic solvents mixtures

Three excess functions (molar volumes, viscosities, and molar enthalpies) for the methyl isobutyl ketone + n-pentanol and methyl isobutyl ketone + isoamyl alcohol systems at 298.15 K were calculated from measured densities, viscosities, and enthalpies, respectively. The UNIFAC group contribution method was used in order to estimate the activity coefficients which were then employed to calculate the excess molar Gibbs free energy. An attempt to explain the experimental results in terms of molecular interactions was made.

Ionic Associates

A new method has been developed for the indirect determination of nitroso- and nitrophenols by atomic absorption spectrometry (AAS) after extraction of ionic associates involving bipyridylocopper(II) (CuDP) or phenanthrolinocopper(II) (CuPH) complexes. Nitrobenzene and methyl isobutyl ketone appeared to be suitable for the extraction. It was possible to determine several tenths to hundredths of a milligram of nitrophenol in a litre. Extractable associates with CuDP and CuPH are formed by phenols possessing two substituents or by higher molecular weight phenols such as naphthol or hydroxyquinoline. Monosubstituted phenols fail to form associates of this kind.
