Environmentally Friendly Approach

The design of the environmentally friendly approach to the synthesis of biologically important compounds without compromising the yield has been the focus of many chemists in recent years. The development of the one-pot synthesis of heterocycles in the presence of Ionic Liquids (ILs), used as both environmental media and catalysts, is efficient and environmentally sustainable. This review highlights the one-pot synthesis of imidazoles in acidic ILs in the past decade. Some reviews have been conducted on imidazoles, such as their pharmacological importance. Hence, we decided to focus on their synthesis in acidic ionic liquids, which the authors are not aware of any published literature.

Selection Of

Solvents are widely recognized to be of great environmental concern. The reduction of their use is one of the most important aims of green chemistry. In addition to this, the appropriate selection of solvent for a process can greatly improve the sustainability of a chemical production process. There has also been extensive research into the application of so-called green solvents, such as ionic liquids and supercritical fluids. However, most examples of solvent technologies that give improved sustainability come from the application of well-established solvents. It is also apparent that the successful implementation of environmentally sustainable processes must be accompanied by improvements in commercial performance.

Solvation Free Energies

In this paper, we calculate solvation free energies of several compounds in ionic liquids. These free energies are used to compute properties such as Henry’s law constants and activity coefficients, generally required in the design of environmentally sustainable processes. It is known, for instance, that carbon dioxide from combustion is one of the main sources of anthropogenic greenhouse gases. Recently, the propensity of the ionic liquid [emim][B(CN)4] for the physisorption of CO2 has been reported, which makes it a potential solvent for carbon capture. In the present work, molecular dynamics simulations of the solvation of CO2 in ionic liquids [emim][B(CN)4] and [emim][NTf2] are carried out both at infinite dilution and at high concentrations. A systematic study is performed by comparing several force fields and assessing the efficacy of simplification measures such as rigid-body dynamics and pairwise electrostatics. Our results confirm recent experimental observations that, for a given volume of solvent, lower pressure is required to absorb a certain amount of CO2 in [emim][B(CN)4] than in other ionic liquids.
