Description:
Objective:The objective of this research is to develop a fundamental and comparative understanding of classes of ionic liquids (ILs) to enable the viable assessment of their utilization in new, environmentally responsible technologies and thus overcome a major barrier to implementation. Thus, the overall goal of this research is to develop and characterize structure-property relationships and elaborate the classification of ILs as solvents to compare and contrast different ILs, to benchmark performance and to discover new applications and uses of ILs. The tasks being undertaken to achieve the objectives are: (1) development of a screening protocol to rapidly study and evaluate all current, new, and emerging commercial ILs; (2) assessment of solute partitioning in IL-organic two-phase systems using Linear Free Energy Relationship analysis to develop ranking and categorization of ILs by solvent characteristics and utility in specific applications; (3) benchmarking of the performance of different, representative ILs, identified using the screening studies above, to provide a set of representative ILs for evaluation; (4) application of clean syntheses of ILs to expand the range of materials for evaluation; and (5) provision of know-how to teach about ILs and their place within the paradigm of Green Chemistry.
Progress Summary:The first toxicity studies appeared relating some design criteria for the synthesis of new ILs. Successful application of ILs was demonstrated for the processing of biomolecule and natural and synthetic polymers. Solid state studies revealed clues to IL behavior and a new delivery vehicle for ILs (gels) was studied. Anion and cation substitution or modification continued to be a major focus of the work.
Future Activities:The basic structure of potential IL salts will be related to specific processes in which they may be utilized as solvents to further characterize their utility in real world application as green solvents. This will be accomplished through solid state characterization of IL salts and directly compared to solvent parameters empirically derived through portioning experiments. The focus will be on the interionic interactions responsible for observed behavior.
