Studies of the phase equilibrium behavior and the excess properties of liquid mixtures are of great importance for the design of separation processes and theoretical understanding of the nature of molecular interaction. While a large numbers of phase equilibria and other mixture properties are available for binary mixtures, the excess properties for ternary mixtures, required to obtain insight into the nature and degree of interactions, are still necessary. In this work, densities and refractive index at 298.15 K are reported for the binary systems {1-Methyl-2-Pyrrolidinone (NMP) +Heterocyclic Nitrogen Compounds}. |
