Process for the preparation of aldehydes |
| abstract |
Abstract of Disclosure The present invention relates to a process for the preparation of aldehydes by the reaction of olefinic compounds with hydrogen and carbon monoxide in the presence of a catalyst system containing rhodium and aromatic phosphines. The aromatic phosphines are soluble in organic media and represent salts of sulfonated or carboxylated triarylphosphines which are insoluble in water. After hydroformylation, the reaction product is treated with a diluted aqueous solution of a base and the aqueous phase containing rhodium and aromatic phosphines is separated. Thus, thermal loading of the catalyst, for example by the redistillation of the reaction product, is avoided. |
