For this purpose a well understood reaction system asymmetric hydrogenation of methyl-3-oxobutanoate (methylacetoacetate/MAA) to methyl-3-hydroxybutanoate (methylhydroxybutyrate/MHB) over the chiral Noyori type Ru-BINAP catalyst in the ethanol-bmimPF(6) reversibly biphasic mixed phase was chosen. Self-prepared bmimPF(6) ionic liquid was exposed to a series of normalized purification steps based on a theoretical semi-mechanistic model. It provided a clear evidence of the number and duration of necessary purification steps together with an effective value of each of them. Another important data were collected in the form of pseudo-ternary phase diagrams for all major components including the model impurities.
