General description

The product is silica gel functionalized with amino groups. The product (3-Aminopropyl-functionalized silica gel) is 9% functionalized and has 1mmol/g of NH2 loading (extent of labelling). It participates as catalyst in the Knoevenagel condensation reactions.

Application

3-Aminopropyl-functionalized silica gel may be used in the following studies:
  • For the separation of polychlorinated biphenyls (PCBs) from lipids by combined supercritical fluid extraction and separation.
  • Preparation of the tin complex immobilized on silica gel, a novel, green, highly efficient and heterogeneous reusable catalyst.
  • Preparation of silica gel bearing isonicotinamide groups.
  • Synthesis of a novel catalytic system including Pd(OAc)2 attached to a bis(oxazoline) ligand that is covalently bonded to 3-mercaptopropyl-functionalized silica gel.
  • Useful as a heterogeneous, reusable catalyst for the Knoevenagel condensation.
  • For low- and medium-pressure reversed-phase liquid chromatography.
