Abstract
A process for preparing oxygenated products comprising aldehydes, which have high normal to branched-chain isomer ratios. The process involves using particularly characterized rhodium-containing complex catalysts under a specific combination of carefully controlled reaction conditions. The product aldehydes as made above may be condensed and hydrogenated to form saturated aldehyde dimers thereof.
