1,152,503. Catalytic hydroformylation of an olefin. JEFFERSON CHEMICAL CO. Inc. 13 June, 1967 [7 July, 1966], No. 27321/67. Heading C2C. Saturated aldehydes and monohydric alcohols are prepared by the hydroformylation of olefins using the oxo process in the presence of a complex catalyst comprising a transition metal and a polyamine containing at least two amino functional groups wherein the amino groups are separated by 1-40 atoms, the molar ratio of polyamine to transition metal being within the range of 0À5:1 to 15:1. The transitional metal may be used in the form of any compound of the metal and preferred metals are Group VIII especially Co, Rh and Fe. The polyamines may be di- or higher alkyl, aryl or heterocyclic polyamines and the amino functions may be primary, secondary, tertiary or contained in an aromatic nucleus or combinations thereof. In heterocyclic compounds the amino functions are preferably not more than 2C atoms apart and in alicyclic or aromatic compounds they are preferably in adjacent C atoms. |
