Densities and Excess Molar Volumes of Ternary Mixtures of N-Methylmorpholine + Aromatic Hydrocarbons At 298.15 K

Abstract

The excess molar volume were calculated from the measured density data over the whole mole fraction range for the ternary systems of N-methylmorpholine (NMM) + benzene + toluene, N-methylmorpholine + benzene + o-xylene, and N-methylmorpholine + benzene + mesitylene and the constituent binary mixtures of N-methylmorpholine + benzene, N-methylmorpholine + toluene, N-methylmorpholine + o-xylene and N-methylmorpholine + mesitylene at 298.15 K under atmospheric pressure. The excess molar volumes of the binary and ternary mixtures were found to be either negative or positive depending on the intermolecular interaction and the nature of liquid mixtures.
