Petrusová, Zuzana ; Morávková, Lenka ; Štefková, V. ; Machanová, Karolina ; Jandová, Věra ; Koštejn, Martin ; Izák, Pavel ; Jansen, J.
This contribution is accomplished by the study of the membrane affinity via contact angle measurements and by structural analysis via electron he transport properties of the TFC PA were studied at various experimental conditions and the obtained results will be discussed.

Mutual Solubilities of Ammonium-Based Ionic Liquids with Water and with Water/Methanol Mixture
Machanová, Karolina ; Jacquemin, J. ; Wagner, Zdeněk ; Bendová, Magdalena
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.

Solubility of Ionic Liquids in Binary Systems with Water and Pseudobinary Systems with Solution Methanol/Water (1:1 Proportion of Weight)
Machanová, Karolina ; Bendová, Magdalena ; Sedláková, Zuzana ; Wagner, Zdeněk ; Aim, Karel
In this work, a study of solubilities of the above-mentioned ionic liquids in binary systems with water and pseudo-binary systems with solution methanol/water (1:1 proportion of weight) is presented. Knowledge of solubility of ionic liquids in these particular systems is helpful in the design and optimization of homogeneous catalytic processes, such as biphasic and reversibly biphasic catalysis. The solubilities were investigated by two experimental methods – the cloud-point and volumetric method.
