Palladium complex with N-heterocyclic carbene ligands

Palladium complex with N-heterocyclic carbene (NHC) ligands is intended for use in catalytic organic synthesis processes, including addition polymerization of norbornenes.

The complex can be used as a source of palladium with a defined ligand environment. Please confirm the specific product form, purity, pack size, dosage, and reaction conditions before ordering.

Role of the material in the process

The catalyst is selected for a specific transformation, feedstock composition, and plant operating mode. The active component, support, and preparation method together determine the availability of active sites. Therefore, specifying the metal or trade name does not guarantee identical activity and selectivity in different processes.

Selection criteria

When comparing options, confirm the content and chemical form of the active component, support type, particle size, moisture, impurities, and pre-activation method. For industrial processes, mechanical strength, pressure drop, and resistance to feedstock components are also important.

Preparation and testing

Before scale-up, test the material under conditions close to operating conditions: with the same feedstock, at comparable temperature, pressure, and contact time. Choose the drying, reduction, calcination, or other activation program according to the documentation. Results can only be correctly compared with identical loading and product analysis methods.

Stability and operation

Water, sulfur compounds, salts, heavy impurities, coking, and overheating can affect the performance of the catalytic system. Acceptable contaminants, signs of deactivation, and regeneration possibilities should be confirmed for the specific grade. Spent material should be collected separately and handled considering the active component composition.
