Hetereocyclic agent as catalytic stabilizing agent in a hydroformylation process

摘要

A heterocyclic nitrogen stabilizing agent is employed to reduce the rate of catalyst deactivation in a hydroformylation process.

主权项

1. A hydroformylation process comprising:
contacting in a reaction zone reactants comprising an olefin, hydrogen and CO in the presence of a metal-triorganophosphine ligand complex catalyst, wherein the metal of the catalyst comprises at least one of rhodium and cobalt, and, optionally, free triorganophosphine ligand, under hydroformylation reaction conditions sufficient to produce an aldehyde product in a reaction fluid, with the proviso that the contacting is conducted in the presence of from 0.001 to 10 weight parts of a heterocyclic nitrogen stabilizing agent based on 100 weight parts of catalyst solution in the reaction zone.
