Removal of Homogeneous Precious Metal Catalysts via Organic Solvent Nanofiltration

Chemical Engineering Transactions, 2016
In homogeneous catalysis often precious transition metal complexes are used. Ideally the used catalyst in a specific process is recovered in the downstreaming and recycled back to the reactor. In contrast to the separation of heterogeneous catalysts, the
