1-butyl-3-methylimidazolium tetrafluoroborate Applications
Bmim BF4 as bulk solvent phases offer new opportunities as recyclable alternatives to conventional organic solvents for biocatalytic production of commercially important chemicals including asymmetric synthesis, with enhancement in certain cases of the rate of product formation and enantioselecfivity.
Bmim BF4 have been applied as enzyme coatings for the development of recyclable heterogeneous biocatalysts, asimmobilized supports for enzymes in biphasic systems employing SCCO2 for continuous reaction systems and as components of supported liquid membranes for continuous separaion of reactants and products in enzyme catalyzed reactions.
