Synthesis, structure-properties relationship and biodegradability assessment of novel protic ionic liquids

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.

Complexation between Aniline and Carboxylic Acids in Hexane

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.

Ionic Hydrogen Bond and Ion Solvation. 6. Interaction Energies of the Acetate Ion with Organic Molecules. Comparison of CH3COO- with Cl-, CN-, and SH-

The interaction energies of CH3COO- with protic and aprotic molecules were measured by pulsed high-pressure mass spectrometry.The attachment energies of the first three water molecules are 15.8, 12.8, and 11.8 kcal/mol.The rapid approach to ΔHcondsn(H2O) shows that ionic interactions are accounted for mostly by the first two solvent molecules.CH3COO- hydrogen bonds strongly to NH acids such as pyrrole, amides, and aniline, with ΔHoD = 25 - 31 kcal/mol.With the carbon acids CH3CHO, CH3COCH3, and CH3CN as ligands, the attachment energies are are 14-16 kcl/mol and the interactions may involve multiple O-..HC bonds.Despite the fact that the ions CH3COO-, Cl-, CN-, and SH- differ in size, structure,electronegativity, isotropy, and available bond sites, they bond with similar strengths to most OH, NH, and CH hydrogen donors, from H2O to large organic molecules such as the dipeptide analogue CH3CO-Ala-OCH3.Also, the four ions show similar clustering energies with n H2O and HCN molecules (n = 1-4).
