Methods to store transition metal organophosphorous ligand based catalysts

A method of preparing a hydroformylation catalyst solution for storage, the catalyst solution comprising:

• A. a transition metal in combination with one or more bisphosphite ligands,
• B. a concentration of acidic species, and
• C. water,
• the method comprising the steps of (i) mixing the catalyst solution with an aqueous buffer solution comprising one or more materials that will neutralize and/or absorb at least 50 percent of the acidic species and (ii) storing the mixed catalyst solution and aqueous buffer solution under a blanket of syngas.
