Temperature Dependence of Physical Properties of Ionic Liquid 1,3-Dimethylimidazolium Methyl Sulfate

Abstract

This paper reports on the synthesis of the ionic liquid 1,3-dimethylimidazolium methyl sulfate [MMIM][MeSO 4 ]. Experimental densities, speed of sounds, and refractive indices were determined from (283.15 to 343.15) K. Dynamic viscosities were measured from (293.15 to 343.15) K. Surface tensions were measured from (288.15 to 313.15) K. The coefficient of thermal expansion and molecular volume of [MMIM][MeSO 4 ] were calculated from experimental values of density.
