An Investigation of the Properties of Binary and Ternary Mixtures Containing Morpholine

The densities of binary and ternary mixtures of morpholine with dimethyl sulfoxide and N -methyl-2-pyrrolidone are experimentally studied at 293.15 K and atmospheric pressure, density deviations and excess molar volumes of mixtures are calculated from experimental data, concentration dependences for binary systems are described by the Redlich–Kister polynomial, and density isoline diagrams of the morpholine–dimethyl sulfoxide– N -methyl-2-pyrrolidone system are plotted.
