Enantioselective liquid-liquid extraction has attracted considerable attention for its potential use in largescale production. Kinetic data are needed for the reliable scale-up of the process. This paper reports the kinetic study of reactive extraction of phenylalanine (Phe) enantiomers with BINAP-copper complex (BINAP-Cu) as a chiral selector. The theory of extraction accompanied by a chemical reaction was applied. The effects of agitation speed
