PROCESS FOR STABILIZING A PHOSPHITE LIGAND AGAINST DEGRADATION |
| 摘要 |
A process for stabilizing a phosphite ligand against degradation in a hydroformylation reaction fluid, said process comprising adding an epoxide to the reaction fluid, and further comprising separating one or more phosphorus acidic compounds from the reaction fluid by treating the reaction fluid with an aqueous buffer solution under conditions sufficient to neutralize and remove at least some amount of the phosphorus acidic compounds from the reaction fluid. |

1. A process for stabilizing a phosphite ligand against degradation in a hydroformylation reaction fluid comprising a metal-organophosphite ligand complex catalyst and the phosphite ligand, said process comprising adding to the reaction fluid from 0.001 to 5 weight percent, based on the weight of the reaction fluid, of an epoxide, and further comprising separating one or more phosphorus acidic compounds from the reaction fluid by treating at least a portion of the reaction fluid with an aqueous buffer solution under conditions sufficient to neutralize and remove at least some amount of the phosphorus acidic compounds from the reaction fluid. |
