Description:
The continuous large-scale preparation of several 1-methylimidazole based ionic liquids was carried out using a Spinning Tube-in-Tube (STT) reactor (manufactured by Kreido Laboratories). This reactor, which embodies and facilitates the use of Green Chemistry principles and Process Intesification, allowed for the solvent-free preparation of a number of high purity, commercially-relevant ionic liquid compounds on the scale of hundreds of grams per hour from the reaction of alkyl halides, tosylates, or triflates with 1-methylimidazole. Upon optimization of the individual reactions, production rates of greater than 15 kg/day have been realized for several of the prepared ionic liquids.
