Densities and Viscosities of Binary Mixtures Containing Methyl Isobutyl Ketone and (C-6-C-10) 1-Alkanol
In the present study, to identify the governing intermolecular interactions in the binary mixtures of methyl isobutyl ketone (MIBK) and 1-alkanols (1-hexanol up to 1-decanol), experimental values of density and viscosity at temperatures (293.15 to 323.15 K) were reported. Excess molar volumes (V-m(E)) and viscosity deviations (Delta eta) for mentioned binary mixtures were calculated and correlated by the Redlich-Kister polynomial expansions. It was found that increasing the alkyl chain of alcohol boosts the strength of intermolecular forces. Also, to obtain more information about the governing forces in the binary mixtures, values of Hansen solubility parameter distance between two molecules, Ra, were calculated, and based on the obtained results, the tendency of alcohol to dissolve in the MIBK media was discussed.
