일반 설명

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

애플리케이션

Recyclable, immobilized catalyst system that simplifies removal of Pd in C-C bond forming and reduction processes.

특징 및 장점

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
