In this work, the systematic study of the physicochemical and excess properties of binary mixtures of carboxylic-based ionic liquids with water is presented. The ILs studied, 1-ethyl-1-methylpyrrolidinium acetate, [EMPYR][AcO]], 1-ethyl-1-methylpyrrolidinium glycolate, [EMPYR][Gly] and 1-ethyl-1-methylmorpholinium glycolate, [EMMOR][Gly] were synthesized in our laboratory, and their structures confirmed by NMR technique. In addition, basic thermophysical characterization of pure ILs was determined using the DSC technique. The density, rho and dynamic viscosity, eta were measured over the entire composition range as a function of temperature from (298.15 to 348.15) K at 101.3 kPa. From the experimental results, excess molar volumes, V-E and dynamic viscosity deviations, Delta eta were calculated and described using the Redlich-Kister equation. The influence of the IL structure on the transport and thermodynamic properties is discussed. (C) 2016 Elsevier Ltd.
