Summary: | Embodiments of the present invention relate to processes to prepare a spent catalyst fluid from a hydroformylation process for precious metal recovery. In one embodiment, a process comprises (a) removing a spent catalyst fluid from an active hydroformylation reaction system, wherein the spent catalyst fluid comprises the hydroformylation reaction catalyst and is substantially free of non-hydrolyzable triorganophosphorous compounds; and (b) adding a non-hydrolyzable triorganophosphorous compound to the spent catalyst fluid from step (a) prior to storing the fluid or prior to shipping for precious metal recovery. |
