Organic Solvent Nanofiltration in Pharmaceutical Applications

Organic Process Research & Development, Journal Year: 2024, Volume and Issue: 28(4), P. 891 - 923

Published: March 22, 2024

Separation and purification in organic solvents are indispensable procedures pharmaceutical manufacturing. However, they still heavily rely on the conventional separation technologies of distillation chromatography, resulting high energy massive solvent consumption. As an alternative, nanofiltration (OSN) offers benefits low consumption, solid waste generation, easy scale-up incorporation into continuous processes. Thus, there is a growing interest employing membrane technology area to improve process sustainability efficiency. This Review comprehensively summarizes recent progress (especially last 10 years) its applications industry, including concentration active ingredients, homogeneous catalyst recovery, exchange OSN-assisted peptide/oligonucleotide synthesis. Furthermore, challenges future perspectives discussed detail.

Rapid and Precise Molecular Nanofiltration Using Ultra‐Thin‐Film Membranes Derived from 6,6′‐Dihydroxy‐2,2′‐biphenyldiamine

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 20, 2024

Abstract A key challenge in efficient molecular separation is fabricating large‐scale, highly selective polymeric membranes with precise pore control at the scale. Herein, a new contorted monomer 6,6′‐dihydroxy‐2,2′‐biphenyldiamine (DHBIPDA) introduced as building block to generate cross‐linked, ultra‐thin microporous nanofilms (sub‐10 nm) via interfacial polymerization, enabling rapid, and nanofiltration. Using diacyl chloride (TPC) cross‐linker instead of trimesoyl (TMC) significantly reduces sizes within achieves narrower distribution due semi‐crystalline structure. The film structures are confirmed using comprehensive characterization techniques including wide‐angle X‐ray scattering (WAXS), diffraction (XRD), positron annihilation lifetime spectroscopy (PALS), CO 2 adsorption analysis, molecular‐scale simulation. DHBIPDA/TPC DHBIPDA/TMC achieve methanol permeance values up 16.4 15.1 LMH bar −1 coupled weight cutoffs (MWCOs) low 283 306 Da, respectively. membrane demonstrates both higher selectivity compared its relatively disordered counterpart DHBIPDA/TMC, consistent data. DHBIPDA‐derived efficiently separates dye mixtures similar weights enables effective recycling organometallic homogeneous catalysts, suggesting potential for industrial applications.

Solvent-resistant crosslinked polybenzimidazole membrane for use in enhanced molecular separation

Journal of Membrane Science, Journal Year: 2024, Volume and Issue: 695, P. 122463 - 122463

Published: Jan. 18, 2024

In molecular separation using membranes, enhanced parameters, such as an increased flux and selectivity, are required for efficiency. Additionally, in solvents, solvent resistance is critical preventing solvent-induced damage. However, most membranes lack resistances to specific harsh simultaneously enhancing selectivity performance, which exhibit a trade-off relationship, challenging. this study, high-performance solvent-resistant polybenzimidazole (PBI) membrane fabricated via chemical crosslinking with divinyl sulfone (DVS). The consists of porous finger-like support dense skin layers, the uniform DVS PBI confirmed analysis. DVS-crosslinked exhibits superior stability ethanol permeance weight cut-off 5.88 L m−2 h−1 bar−1 483 g mol−1, respectively. These values represent rejection performance compared those pristine membrane. also displays long-term mepenzolate bromide over 72 h.
