ABSTRACT:
Metallic catalysts such as Group VIII metal complexes which are used in hydroformylation reaction for the production of alcohols from olefins will be found in the product mixture. The separation and recovery of these metal catalysts from the product mixture may be accomplished by treating said product mixture with a biphyllic ligand capable of forming a soluble complex with the metallic catalyst and thus can be removed from the desired product.
