PROCESS FOR THE SEPARATION OF COBALT FROM PRIMARY PRODUCTS OF THE OXO-SYNTHESIS AND RECIRCULATION EOF TO THE SYNTHESIS STAGE

摘要

A process for the separation of cobalt from the primary products of the Oxo-synthesis, which products contain dissolved cobalt-carbonyl compounds, which comprises adjusting the sulfur content of the primary products so that the sulfur content is at least 15 mg/kg of primary product and subjecting the primary products containing sulfur in at least said amount to a steam treatment and separating precipitated cobalt therefrom.
