Hydroformylation catalysts Rh-42, Rh-43 (ROPAC) and Rh-50

Our rhodium hydroformylation catalysts are air stable, contain no halide and have good solubility in organic solvents. They are normally used with ligands such as triphenylphosphine.

ROPAC has a higher rhodium content than Rh-42 and has been used for hydroformylation since the development of the low pressure oxo process in the 1970’s.

Rh-50 is more hazardous than ROPAC and has a significant vapour pressure. It should be handled with appropriate precautions.
