Abstract
This invention concerns an oxo process employing unmodified rhodium catalyst for the preparation of aldehydes, principally for the preparation of relatively high proportions of branched isomer, from olefins and synthesis gas. More particularly the invention concerns such a process wherein at least a portion of the reaction medium, e.g., the oxo reactor effluent, is contacted with an oxygen containing gas prior to product recovery by distillation, such that the rhodium is converted to a stable form and not lost by plating out on the distillation column or base heater during the distillation.
