Zusammenfassung:	To provide a means of separating high-boiling aldehydes from a rhodium-organophosphite hydroformylation catalyst while reducing the loss of rhodium.SOLUTION: A continuous hydroformylation process includes: (a) removing a reaction fluid from a reactor 100; (b) sending the reaction fluid to a vaporizer 200; (c) separating the reaction fluid in the vaporizer to produce a catalyst-containing liquid stream and a gas phase stream; and (d) maintaining an average CO partial pressure in the vaporizer of greater than 16 psia (110 kPa).SELECTED DRAWING: Figure 1 【課題】ロジウム消失を低減しつつ、ロジウム−オルガノホスファイトヒドロホルミル化触媒から高沸点のアルデヒドを分離する手段の提供。【解決手段】連続ヒドロホルミル化プロセスであって、（ａ）反応流体を反応器１００から除去することと、（ｂ）前記反応流体を気化器２００に送ることと、（ｃ）前記気化器内の前記反応流体を分離して、触媒含有液体流及びガス相流を生成することと、（ｄ）前記気化器内の平均ＣＯ分圧を１６ｐｓｉａ（１１０ｋＰａ）より高く維持することとを含む、連続ヒドロホルミル化プロセス。【選択図】図１
