In the present study, the design, synthesis and biodegradability assessment of 14 protic ionic liquids (PILs), among which nine are presented for the first time in bibliography, is presented. Furthermore, since PILs are considered as alternative green solvents with favorable properties for a variety of applications, we herein report the study of two of the most important PILs physicochemical properties, thermal behavior (melting, cold crystallization and glass transition temperatures) and viscosity. The effect of selected structural features of the PILs ions (such as the aromatic and alicyclic ring, the ions size and the presence of hydroxyl groups) on the above-mentioned properties has been also discussed.

The influence of the concentration factor on attainment of equilibrium complexation of aniline with carboxylic acids in hexane was examined by UV spectroscopy.Three acid concentration regions are distinguished: at low concentrations, the complexation process escapes detection; with an increase in the acid concentration, the equilibrium constant becomes finite, but variable; and in the third region, the equilibrium constant attains a steady-state value.This is attributable to the effect of the medium on the acid monomer-dimer equilibrium.It is shown that one can select the conditions for kinetic studies under which the complexation reaction could be neglected.
