ABSTRACT:
A hydroformylation process which comprises hydroformylating an olefinic compound by reacting it with water gas in a catalyst solution containing rhodium and an oxide of an organic trivalent phosphorus compound; adding an organic trivalent phosphorus compound to the reaction mixture, followed by distillation to separate a distillate containing the hydroformylation product from a high-boiling residue containing rhodium; oxidizing the high-boiling residue at the same time as or subsequent to the distillation, to convert the organic trivalent phosphorus compound to its oxide; and recycling the oxidized residue to the hydroformylation reaction zone.
