Abstract

Abstract: In homogeneous catalysis, the application of organic solvent nanofiltration (OSN) has become a well‐known alternative to common recycling methods. Even though some OSN membranes are commercially available, their classification and the scope of application have to be determined for the specific solvent mixture. The commercial membrane Evoniks DuraMem® 300 was tested in a mixture of ethanol, ethyl acetate, and cyclohexane with magnesium triflate as possible catalyst. The cross permeate fluxes were measured for two transmembrane pressures and the hydrodynamic radii of the components were determined. Some of the components in the ternary mixture are retained, which makes the membrane also suitable for fractioning thereof. Abstract : Organic solvent nanofiltration (OSN) has become a promising alternative to common recycling methods in homogeneous catalysis. Its applicability was tested with the commercial Evoniks DuraMem® 300 membrane, optimal solvent compositions were identified, and standard parameters were determined. OSN with such a membrane proved to be well‐suited for catalyst recycling.
