摘要：

The authors prepared, characterized and preliminary studied the properties of some neoteric solvents-ionic liquids based on choline chloride, i.e.., three ionic liquids based on the eutectics of choline chloride(2-hydroxy-N,N,N-trimethylethanaminium chloride) with, respectively, urea, malonic acid and citric acid. The obtained mixtures' were clear and colorless ionic liquids at room temperature. The thermophysical properties, namely, density, viscosity, and electrical conductivity of these mixtures were investigated as a function of temperature within a range of 298-353 K. Correlations for the temperature dependence of the measured properties were generated and discussed in terms of Arrhenius theory. Finally the electrochemical windows of the eutectic liquids were determined.
