Abstract
Abstract A novel, heterogeneous catalyst is useful in an improved process for the production of aldehydes and alcohols from olefinic hydrocarbons in the presence of carbon monoxide and hydrogen. The catalyst consists of a polyphenylene substrate to which are bonded diphenylphosphine ligands complexed with a metal carbonyl, such as cobalt carbonyl. The catalyst has excellent thermal stability, is essentially insoluble in the reactants or reaction products, and is active in the hydroformylation reaction at a temperature of about 195° C and a pressure of about 500 psig.
