The paper reports for the first time the experimental densities of binary liquid (glycerol (1) + N,N-dimethylacetamide (2)) mixtures measured over the whole composition range at atmospheric pressure at (278.15, 283.15, 288.15, 293.15, 298.15, 308.15, 323.15 and 333.15) K. These data are used to calculate the excess molar volumes of the mixture and partial molar volumes of glycerol (GL) and N,N-dimethylacetamide (DMAA), coefficient of thermal expansion and molar isobaric thermal expansion of the mixture. The number of controlled parameters included in the Redlich-Kister polynomial for fitting the excess molar volumes is optimized using an F-test. The formation of the glycerol + N,N-dimethylacetamide mixture is accompanied by volume reduction at all the temperatures, and as the temperature increases, the deviation from ideality becomes greater. The temperature dependencies of the limiting molar isobaric expansion coefficients of glycerol and N,N-dimethylacetamide are not unidirectional.
