Abstract

A linear model based on group-interaction contributions is proposed for the estimation of the freezing temperature (Tf) of ionic liquids (ILs). This property is important for modelling solid-liquid equilibrium and selecting ionic liquids as reaction media among other things. A database of 66 experimental freezing points different ionic liquids was used to obtain all interaction contribution parameters and model constants. The database included various classes of ionic liquids and a wide range of cation and anion groups., with an average absolute relative deviation of 4,09% and a correlation coefficient of 0,93.
