PROCEDE POUR LA RECUPERATION DU COBALT DE PRODUIT DE REACTION DE HYDROCARBOXYLATION

摘要

1. A process for working-up a cobalt-containing distillation bottoms product which has arisen in the working-up by distillation of a reaction mixture obtained by reaction of an olefin with carbon monoxide and water or an alkanol in the presence of a cobalt-containing catalyst and a promoter and subsequently oxidised, characterised in that the cobalt-containing residue arising as distillation bottoms product is hydrogenated, the resulting metallic cobalt is separated and reacted with an acid and the cobalt salt formed is optionally converted into another cobalt salt.
