Abstract (EN): In this paper, the ionic liquids 1,2-diethylpyridinium ethylsulfate, EEpyESO(4); 1-methylpyridinium methylsulfate, MpyMSO(4); 1,3-dimethylpyridinium methylsulfate, MMpyMSO(4); and 2-ethyl-1-methylpyridinium methylsulfate, EMpyMSO(4); were synthesized in our laboratory, and their experimental densities, speeds of sound, dynamic viscosities, and refractive indices were studied as a function of temperature at atmospheric pressure. Thermal expansion coefficient, molar volume, and molar refraction of these ionic liquids were calculated from the experimental density and refractive index values.
