Systematic Comparison of Homogeneous Catalyst Recycling Strategies: Organic Solvent Nanofiltration vs. Liquid-Liquid-Multiphase. [PDF]
ChemistryKey performance metrics, including hexene conversion rates and catalyst leaching, were evaluated over extended continuous operation periods. Results demonstrated that the OSN method significantly outperformed the multiphasic system, maintaining hexene conversion at 83% after 76 h compared to a decline to 72% in the multiphasic setup after 36 h ...

Microporous Polymer Membranes: Molecular Stents Enhanced Solvent-Accessibility for Organic Solvent Transport. [PDF]
Adv Sci (Weinh)A novel microporous polyimide (PI‐TB‐NDI) is designed for enhanced organic solvent nanofiltration. By incorporating o‐methyl groups into the Tröger's base (TB) unit to create molecular stents, the polymer's intrinsic free volume is effectively increased without the need for post‐treatment.
