ABSTRACT

In order to have better insight into the structure property relationship and promote the development of the potential applications of ionic liquids, it is essential to obtain more physicochemical property data. In this research, densities and viscosities of the binary mixtures of 1, 3-dimethylimidazolium dimethylphosphate ([Mmim][DMP]) and the alcohol (methanol, ethanol, propanol, or isopropanol) were measured within the temperature range from (293.15 to 323.15) K. The densities of these four mixtures were fitted by an empirical linear equation, and their viscosities were fitted by Vogel Fucher Tammann (VFT) equation. Moreover, the excess molar volumes (VE) and viscosity deviation (??) of four binary mixtures were calculated and fitted by a Redlich Kister equation. In addition, the interactions and structure factors in these binary mixtures were discussed in detail based on the results. The results indicate that the obtained excess molar volumes and viscosity deviations for the four mixtures are negative at investigated temperatures.
