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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
