Impact of minor amounts of hydroperoxides on rhodium-catalyzed hydroformylation of long-chain olefins

Author affiliations

Abstract

The effect of minor amounts of impurities on the course of chemical reactions is often overlooked. Analyzing commercial 1-dodecene feeds, hydroperoxides were identified as critical impurities. The influence of varying hydroperoxide concentrations in olefin feeds was systematically investigated, experimentally studying rhodium-catalyzed hydroformylation using a diphosphite ligand. A significant loss of n-aldehyde selectivity and linear-to-branched ratio (l/b) was observed for increasing hydroperoxide concentrations. Feeding of an additional ligand and/or purification of 1-dodecene restored the catalyst performance.
