Membrane filtration is an attractive approach for soluble catalyst recycling. Applications of nanofiltration have demonstrated their great potential as a method for process intensification in enzyme, organo-, and homogeneous catalysis, both in laboratory practice and on an industrial scale. Selected, recent advances in catalyst recovery by means of membrane filtration are discussed, together with their implication for future developments. These examples demonstrate that this strategy is applicable in many different transformations.

“…Sheth et al 165 claimed that precompacting commercial MPF-50 or MPF-60 with used solvents at operational pressures and temperatures is necessary to remove erythromycin because precompaction increased the rejection of erythromycin by SRNF membranes, which reduced the loss of erythromycin and increased the purification efficiency. Shi et al 166 fabricated a type of PI membrane to concentrate spiramycin 220 (n-alkanes in toluene) [168][169][170][171][173][174][175]180,182,184,[190][191][192]195,197 Starmem TM 228 280 (n-alkanes in toluene) 169,179,184,196 Starmem TM 240 400 (n-alkanes in toluene) [171][172][173][174][175]180,182,184,185,189,196,197 Puramem TM extracts and recover the used solvent (butyl acetate). They indicated that the permeability of the spiramycin solution was significantly affected by the operating conditions, although the rejection of spiramycin (higher than 99%) was not influenced.…”

Recent Advances in Polymeric Solvent‐Resistant Nanofiltration Membranes

When considering energy consumption and environmental issues, solvent-resistant nanofiltration (SRNF) based on polymeric materials emerges as a process for substituting conventional separation processes of organic solutions, such as distillation, which consume high amounts of energy. Because SRNF does not involve phase transition, this process can potentially decrease the energy consumption and solvent waste and increase the yield of active components. Such improvements could significantly benefit a number of fields, such as pharmaceutical manufacturing and catalysis recovery, among others. Therefore, SRNF has gained a lot of attention since the recent introduction of solvent-stable polymeric materials in the manufacture of nanofiltration membranes. The membrane materials and the membrane structures depending on the fabrication methods determine the separation performance of polymeric SRNF membranes. Therefore, this article gives a comprehensive overview of the current state-of-art technologies of generating membrane materials and corresponding fabrication methods for SRNF membranes made from polymeric materials expected to provide the most benefit. The transport mechanisms and the corresponding models of SRNF membranes in organic media are also reviewed to better understand the mass transfer process. Various SRNF applications, such as in pharmaceutical and catalyst, among others, are also discussed. Finally, the difficulties and future research directions to overcome the challenges faced by SRNF processes are proposed. C

“…However, to date, industrial Rh‐catalyzed hydroformylation processes are often limited to olefin substrates smaller than C5 carbon chains. This motivates some studies about the conversion of linear long‐chain olefins . This case study deals with the improvement of a hydroformylation process for the conversion of biosourced 10‐undecenitrile into 12‐oxo‐dodecanenitrile as a route toward polyamide‐12 (Figure ).…”

Coupling Rhodium‐Catalyzed Hydroformylation of 10‐Undecenitrile with Organic Solvent Nanofiltration: Toluene Solution versus Solvent‐Free Processes

et al. 2019

Intensification of the rhodium‐catalyzed hydroformylation process to produce 12‐oxo‐dodecanenitrile from biosourced 10‐undecenitrile was performed by coupling the reaction with organic solvent nanofiltration (OSN) for the recycling of the expensive Rh catalyst and the ligands. Four phosphorus‐based ligands were compared with respect to their catalytic performance and rejection in OSN. Biphephos showed the best compromise and up to 3 reaction‐OSN cycles were performed in toluene. A good recycling of the catalytic system was evidenced arising from the OSN (up to 88 % rejection). In order to develop a greener process, a similar approach was achieved in bulk (i. e. solvent‐free medium), thus proving the catalyst recycling feasibility but also that the optimal OSN conditions are not the same as for toluene. Finally, integration of OSN in the overall production process is discussed, aiming at the proposal of a hybrid separation process involving a combination of OSN and distillation for an energy‐efficient separation step.
