Title:
HETEROCYCLIC AGENT AS CATALYTIC STABILIZING AGENT IN HYDROFORMYLATION PROCESS
Document Type and Number:
Japanese Patent JP2017226663
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a continuous catalyst activity maintenance process in hydroformylation sufficient to form at least one aldehyde product in the presence of a catalyst comprising a transition metal and a triorganophosphine ligand.SOLUTION: A hydroformylation process comprises: contacting in a reaction zone reactants comprising an olefin, hydrogen and CO in the presence of a triorganophosphine ligand complex catalyst, where the metal of the catalyst comprises at least one of rhodium and cobalt, and, optionally, a free triorganophosphine ligand, under hydroformylation reaction conditions sufficient to produce an aldehyde product in a reaction fluid, with the proviso that the contact is conducted in the presence of 0.001 to 10 pts.wt. of a heterocyclic nitrogen stabilizing agent based on 100 pts.wt.of a catalyst solution in the reaction zone.SELECTED DRAWING: None
