Abstract

A novel and facile synthesis of ionic liquids and organic salts is achieved via metathesis of organoions in dilute isopropanol that is partitioned from ion-driven supersaturation of sodium chloride. Confirmation of high yield ionic liquids and organic salts is fulfilled by characterization using ESI-MS, FT-IR, NMR, TGA, amongst many others. This proposed method, compared to the previously used DCM-Water two-phase metathesis, increases the Analytical GREEnness (AGREE) metric by + 0.10.
