Title: Excess enthalpies and excess volumes for n-butyl methyl ether + n-alkane systems at 298.15 K.
Author: Wang, Luo.
Abstract: Research on excess properties plays an important role in solution thermodynamics. The experimental excess properties of liquid mixtures provide essential information for testing and developing solution theories. They also provide the data required for process design in chemical and petroleum industries. In addition excess properties are useful for testing thermodynamic consistency for vapor-liquid equilibrium data. Both excess enthalpies $H\sp{E}$ and excess volume $V\sp{E}$ were determined in this study for six binary systems consisting of n-butyl methyl ether and an n-alkane at 208.15 K. Flory theory with an interaction parameter, which was found to be a quadratic function of the carbon number of the n-alkane molecules, was used to correlate the experimental $H\sp{E}$ data and then to predict $V\sp{E}$ values which were subsequently compared with the experimental $V\sp{E}$ data.
