Abstract: This work presents a study on solubility in water and in water/methanol mixture of a set of ILs composed of the bi (trifluoromethylsulfonyl)imide anion and of the N-alkyl-triethyl-ammonium cation (abbrev. [NR222][NTf2]) with the alkyl chain R ranging from 6 to 14 carbons. These ILs were successfully tested for enantioselective hydrogenation of β-ketoesters catalyzed by the chiral complex Ru-BINAP in presence of methanol [1]. From which, it appears that these ILs immobilise the catalyst in the mixture for easier recycling and further re-use and protect it from air/oxygen. The final separation of the product is carried out by rinsing the solution with water, which may also wash out the ILs with catalyst. For this reason, mutual solubilities between ILs and water, as well as between ILs and methanol/water mixture need to be investigated in detail.
