PROBLEM TO BE SOLVED: To provide a continuous catalyst activity maintenance process in hydroformylation sufficient to form at least one aldehyde product in the presence of a catalyst comprising a transition metal and a triorganophosphine ligand.SOLUTION: A hydroformylation process comprises: contacting in a reaction zone reactants comprising an olefin, hydrogen and CO in the presence of a triorganophosphine ligand complex catalyst, where the metal of the catalyst comprises at least one of rhodium and cobalt, and, optionally, a free triorganophosphine ligand, under hydroformylation reaction conditions sufficient to produce an aldehyde product in a reaction fluid, with the proviso that the contact is conducted in the presence of 0.001 to 10 pts.wt. of a heterocyclic nitrogen stabilizing agent based on 100 pts.wt.of a catalyst solution in the reaction zone.SELECTED DRAWING: None 【課題】遷移金属及びトリオルガノホスフィンリガンドを含む触媒の存在下で少なくとも１つのアルデヒド生成物を形成するのに十分なヒドロホルミル化における連続的触媒活性維持プロセスの提供。【解決手段】ヒドロホルミル化プロセスであって、トリオルガノホスフィンリガンド錯体触媒の存在下で、オレフィン、水素、及びＣＯを含む反応物質を、反応領域内で接触させることであって、前記触媒の金属が、反応流体中でアルデヒド生成物を生成するのに十分なヒドロホルミル化反応条件下で、ロジウム及びコバルトのうちの少なくとも１つ、ならびに随意に、遊離トリオルガノホスフィンリガンドを含むが、但し、前記接触させることが、前記反応領域内の１００重量部の触媒溶液に基づいて０．００１〜１０重量部のヘテロ環式窒素安定剤の存在下で行われることを条件とする、接触させること、を含む、前記プロセス。【選択図】なし
