Excess Thermodynamic Function

The viscosities, densities, and refractive indices at 20, 25, 30, and 35 °C were determined for the systems: methyl isobutyl ketone–n-butanol (MIK–B1), methyl isobutyl ketone–sec-butanol (MIK–B2), and methyl isobutyl ketone–isobutanol (MIK–B3). From the experimental results the excess volume, excess viscosity, and excess molar free energy of activation of flow were calculated. The deviations from ideality for the excess thermodynamic function are more important for the system (MIK–B2) than for the systems (MIK–B3) and (MIK–B1). This fact is explained by the existence of hydrogen bonds in the alcohols, stronger in the primary alcohols than in sec-butanol.

Experimental Values

Experimental values of density and speed of sound for binary liquid mixtures of 2,5-dimethylfuran (2,5-DMF) with furfuryl alcohol (FA), methyl isobutyl ketone (MIBK), 1-butanol and 2-butanol and over the entire composition range of 2,5-DMF and at the temperature range of 293.15–323.15 K at 10 K intervals and at pressure p = 0.1 MPa were reported. Experimental data were used to assess the thermodynamics properties of studied mixtures. These properties were used to interpret the molecular interactions among component of liquids. The values of excess/deviation functions have been fitted to Redlich−Kister type polynomial equation. From the obtained results, a discussion was carried out in terms of nature of intermolecular interactions and structure factors in the binary mixtures.

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.
