In my thesis I discussed the physico-chemical properties of the 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid. Experimental data for thermal capacity, viscosity and density of temperature dependence were obtained from literature sources. I calculated the dependance of this same parameters using model equations, developed by group contribution method, and evaluated if the method accurately predicts the behavior of the ionic liquid. Experimental and calculated data matched well in the case of density and heat capacity, as there were minor deviations. However, major deviations occurred in viscosity.
