摘要:
A process for improving the catalytic activity of a partially deactivated solubilized rhodium-tertiary organophosphine complex hydroformylation catalyst by treating it with propargyl alcohol and a carboxylic acid.
摘要:
An improved rhodium-organophosphite complex catalyzed hydroformylation process, the improvement comprising carrying out said process in the presence of a catalytic activity enhancing additive said additive being selected from the class consisting of added water, a weakly acidic compound, or both added water and a weakly acidic compound.

摘要:
This invention provides a process for stabilizing a phosphite ligand against degradation in a homogeneous reaction mixture containing a Group VIII transition metal catalyst and the phosphite ligand, said process comprising adding to the reaction mixture an epoxide in an amount from 0.001 to 5 weight percent based on the total weight of the reaction mixture to reduce the degradation of the ligand.
