Synthesis of Ionic Liquids Equipped with 2-Methoxyethoxymethyl/Methoxymethyl Groups Using a Simple Microreactor System

A simple microreactor system has been utilized for the continuous flow synthesis of novel ionic liquids having a (2-methoxyethoxy)methyl or methoxymethyl substituent. Conversion rates of N-bases and tributylphosphine in the microreactor system are faster than those in the batch system because of less diffusion distance in the tube reactor. This method allows us to prepare ionic liquids in efficient yields with high purity.
