Descrizione generale

1-Ethyl-1-methylpyrrolidinium bromide is an ionic liquid that can be prepared by reacting N-methylpyrrolidine with bromoethane. it is conventionally used as a bromine-sequestering agent (BSA) in zinc/bromine redox flow batteries.

Applicazioni

1-Ethyl-1-methylpyrrolidinium bromide may be used in the preparation of 1-ethyl-1-methylpyrrolidinium lactate, a potential solvent for the separation of hexan-1-ene from hexane. It can also be used to prepare 1-ethyl-1-methylpyrrolidinium tribromide. It can be used as a co-catalyst during the cycloaddition of CO2 with different epoxides to form cyclic carbonates in the presence of a nona-vacant Keggin-type tricarbonyl rhenium derivative catalyst.
