METHODS TO STORE TRANSITION METAL ORGANOPHOSPHOROUS LIGAND BASED CATALYSTS. |
摘要 |
The catalyst solution used in a hydroformylation process is prepared for storage by first reducing its acid concentration and/or water content, and then storing the solution under a blanket of syngas and/or an inert gas. Alternatively, or in addition to, the catalyst solution can be stored with an aqueous buffer comprising materials that will neutralize and/or absorb the acid species within the catalyst solution. |
