The design and synthesis of high efficiency adsorption materials for 1,3-propanediol: physical and chemical structure regulation

Abstract

Chemically modified materials efficiently captured 1,3-propanediol via the specific affinity between boronic acid and diol.

MIL-53 and its OH-bonded variants for bio-polyol adsorption from aqueous solution

“…Generally, polyol adsorption on resins, MOFs and ZSM-5 ref. 11,21,39,40 needs 4–24 h to reach adsorptive equilibrium based on earlier literature. Clearly, MIL-53 and OH–MIL-53 enjoy advantages in terms of adsorption kinetics, as they are not sensitive to particle size.…”

“…16,17 However, adsorbents with high capacity along with recyclability towards high-boiling-point polyols have been rarely reported. 11,18–22…”

“…16,17 However, adsorbents with high capacity along with recyclability towards high-boiling-point polyols have been rarely reported. 11,[18][19][20][21][22] Connecting metal ions and organic linkers in a periodic network affords metal-organic frameworks (MOFs) with permanent high porosity. Their modular chemistry encourages the diversity of MOFs.…”

Co-production of 1,3-propanediol and phage phiKpS2 from the glycerol fermentation by Klebsiella pneumoniae

“…The conventional separation of 1,3-PDO from fermentation broths, including steam evaporation (Ames 2002), vacuum distillation (Zhang et al 2021), ion-exchange chromatography (Zheng et al 2020) and reactive extraction (Li et al 2009b), is difficult to adapt to simultaneous separation of phage. On the other hand, downstream processing of phages is a complex, time-consuming and expensive process, including precipitation (Salim et al 2021), centrifugation (Jacinto et al 2018), filtration (Salim et al 2021), chromatographic techniques (Clavijo et al 2019), and so on.…”
