Thermodynamics of mixtures with a hexane isomer. Excess volumes of 1-chlorohexane with a hexane isomer at 298.15 K

Abstract

The excess volumes of 1-chlorohexane with a each of five hexane isomers have been measured at 298.15 K using a vibrating-tube densimeter. The results have been correlated using several generalized van der Waals models, including random and non-random distribution of the molecules, as well as lattice-with-holes models. None of the models is clearly superior to the other, and all of them give very poor predictions of non-fit excess properties for systems of an alkane with a hexane isomer.
