Densities and Excess Volumes of the 1,3-Dimethylimidazolium Methylsulfate + Methanol System at Temperatures from (313.15 to 333.15) K and Pressures from (0.1 to 25) MPa
Densities of pure 1,3-dimethylimidazolium methylsulfate ionic liquid [MMIM][CH3SO4] and its mixtures with methanol have been measured with an accuracy of +-0.2 kg*m-3 over a temperature range from (313.15 to 333.15) K and a pressure range from (0.1 to 25) MPa using a vibrating tube densimeter. The isothermal compressibilities, isobaric expansivities, and excess volumes have been calculated. The uncertainties of these properties have been estimated to be +-0.05 GPa-1, +-0.2*10-4 K-1, and +-0.1 cm3*mol-1. The exceptionally strong influence of pressure and temperature on the excess volumes has been observed.
