Allgemeine Beschreibung

It is an encapsulated catalyst (EnCat®), wherein palladium acetate is microencapsulated within a polyurea matrix, which prevents palladium leaching.

Anwendung

Reaxa Technology
Recyclable, immobilized catalyst system that simplifies removal of Pd in C-C bond forming and reduction processes.
While Pd EnCat 40 shows excellent performance in a variety of transformations, Pd EnCat 30, with lower matrix content, shows similar performance but with improved kinetics while maintaining the mechanically robust nature of Pd EnCat 40 under similar conditions.

Leistungsmerkmale und Vorteile

The advantages of using Pd EnCat® catalysts are:
  • low residual metal levels in crude product
  • easy recovery of catalyst
  • compatibility of immobilized metal with various ligands to effect C-C bond forming reactions
  • safer and easier to handle than Pd/C for hydrogenation
  • efficiency and economy gains through recovery and recycling
