Systematic Comparison of Homogeneous Catalyst Recycling Strategies: Organic Solvent Nanofiltration vs. Liquid‐Liquid‐Multiphase

open access: yesChemistry – A European Journal, Volume 32, Issue 6, 9 February 2026.
Key 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 ...
