Zusammenfassung
Thirty-nine different Ionic Liquids were synthesized, with symmetric quaternary ammonium cations and alkylethercarboxylates as anions. Similar to the recently published Concept of Melting Point Lowering due to Ethoxylation, here propoxyethylene groups, PO groups, in the anions allow a wide range of salts being liquid at or dose to room temperature. The physical chemical properties, density, ...
