Ultrasonic speeds and isentropic compressibilities of 2-methylpentan-1-ol with hexane isomers at 298.15 K

Ultrasonic speeds were determined for binary mixtures of 2-methylpentan-1-ol with n-hexane and each of its four isomers. Measurements were made over the whole mole-fraction range with particular attention given to the region of high dilution with respect to the alcohol. The results were combined with excess molar volumes reported previously to obtain values of the excess molar quantity $\text{K}{}_{\mathrm{<mtext>S,</mtext><mtext>m</mtext>}}{}^{\mathrm{<mtext>E</mtext>}}\text{= ?(}\text{?V}{}_{\mathrm{m}}{}^{\mathrm{E}}\text{?p}\text{)}{}_{\mathrm{s}}$ and the corresponding partial molar derivatives.
