ResumoThe excess molar volumes, [Formula: see text], of 2-hexanone (MBK) with n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, n-dodecane, and n-tridecane have been obtained at 298.15 K from densities measured with a vibrating tube densimeter. The [Formula: see text] are positive over the entire composition range in all mixtures, with the exception of the MBK + n-hexane system, where an inversion of the sign of [Formula: see text] is observed. In other systems, [Formula: see text] increases with increasing size of the alkyl group in n-alkane.
