Application

  • Water-insoluble β-cyclodextrin–epichlorohydrin polymers for removal of pollutants: This review article discusses the use of β-cyclodextrin–epichlorohydrin polymers in sorption processes to remove pollutants from aqueous solutions (N Morin-Crini, P Winterton, S Fourmentin, 2018, Progress in Polymer Science).
  • Eco-efficiency improvements in the propylene-to-epichlorohydrin process: This research provides an analysis of improving the eco-efficiency of the propylene-to-epichlorohydrin production process, which is crucial for industrial applications like windmill blade manufacture (Ł Madej, AA Kiss, 2023, Journal of Chemical Technology & Biotechnology).
