The new densities of binary mixtures of dimethyl sulfoxide (DMSO) with primary, secondary, and tertiary amines {2-aminoethanol (MEA), 2,2′-iminodiethanol (DEA), and bis(2-hydroxyethyl)methylamine (MDEA)} were measured at the atmospheric pressure for the temperatures ranging from (293.15 to 363.15) K over the entire composition range using an Anton Paar digital vibrating U-tube densimeter (model DMA 5000 M). A Redlich–Kister type equation was correlated using the excess molar volumes calculated with the experimental values and used to represent the densities of the liquid mixtures as a function of temperature and concentration. The thermal expansion coefficients of the pure components along with their binary mixtures using the experimental data are represented and discussed.
► Volumetric properties of mixtures of dimethyl sulfoxide with amines were studied.
► The excess molar volumes have been correlated using the Redlich–Kister equation.
► A set of parameters for the Redlich–Kister equation has been determined.
► The thermal expansion coefficients are represented and discussed.
