Abstract

Production of aldehydes and alcohols by hydroformylation of olefinically unsaturated compounds with carbon monoxide and hydrogen at elevated temperature and superatmospheric pressure in the presence of carbonyl complexes of metals of group 8 of the Periodic System which have been modified with trisubstituted phosphines in which two substituents are lower alkyl radicals and the third substituent is a higher aliphatic radical. Aldehydes and alcohols are known to be solvents; they are used on a large scale for the production of plasticizers for polyvinyl chloride.
