Abstract
The extraction process for removing metal salts from an organic hydroformylation reaction fluid ('HRF') prior to returning the HRF to a reaction zone of a hydroformylation process, the extraction process comprising the step of contacting the HRF with an aqueous buffer solution, is improved by contacting the HRF with water in addition to that present in the aqueous buffer solution, i.e., with added water.
