Improved hydroformylation process separation and recycle of active rhodium catalyst.

摘要

FROM A CURRENT hydroformylation catalyst containing organo-RODIO active and inactive, is separated active rhodium catalyst and impurities, JOINING SUCH ACTIVE CATALYST AND SUCH impurities, exchange resin acidic ion, containing a group ACID. CURRENT PURIFICADA hydroformylation, can be forwarded to the hydroformylation reactor. ALL OR A FRACTION OF RODIO IDLE, can be reactivated before recycling to the reactor CURRENT PURIFICADA hydroformylation process. During production of the resin, a solvent USED NEUTRAL to remove impurities, which are discarded, BEING TOLD then it used solvent to remove RESIN CATALYST ORGANIC ACTIVE RODIO. Said active catalyst may be rehydrated and returned to the hydroformylation reactor. It can thus produce a resin ion exchange with at least one acid group ON A SKELETON SILICEO WILLING, AND ORGAN-RODIO COMPLEX FROM A CURRENT ASSETS hydroformylation resin bound.
