  • Process to prepare a linear aldehyde
    Patent number: 5710344
    Abstract: The invention relates to a process for the preparation of linear aldehydes by hydroformylation of ethylenically unsaturated organic compounds in the presence of a catalyst system comprising a Group VIII metal and a bidentate organic ligand. The bidentate organic ligand is characterized in that it has two trivalent phosphorus atoms each containing at least one P--C or one P--N bond.
