Carbonate Based Ionic Liquid Synthesis (CBILS®): development of the continuous flow method for preparation of ultra-pure ionic liquids

Abstract

Carbonate Based Ionic Liquid Synthesis (CBILS®) is one of the most advanced commercialized processes for greener and halide-free technical synthesis of ionic liquids (ILs). To meet the increasing demand for high purity ILs, a continuous flow method with an improved space-time yield was developed. The quality of resulting ILs and IL-intermediates was confirmed to be ultra-high, by traditional analytical methods as well as by extremely sensitive combustion and solution calorimetry techniques.
