Brief Introduction of IL and Synthesis of [DBU][Ac] and PEG-DIL

The present book describes the brief introduction of ionic liquids. [DBU][Ac] synthesized through the simple neutralization reaction of equal molar amounts of DBU and acetic acid under ultra-sonication. PEG-DIL was prepared by reacting PEG-600 with 1-butylimidazole. synthesis of PEG-DIL split into two steps. The first step involves synthesis of PEG-600-OSO2CH3 via a reaction of PEG600 with methanesulfonyl chloride and second step was a nucleophilic substitution between PEG600-OSO2CH3 and 1-butylimidazole to generate the desired PEG functionalized dicationic ionic liquid. Characterization of [DBU][Ac] and PEG-DIL by NMR spectroscopic data.
