ABSTRACT:
A process for separating carbon black from a liquid containing it is disclosed wherein a particular amount of an oxygen containing higher boiling product which is the non-volatile residue produced as a by-product of the oxo-synthesis is added to the liquid whereby the carbon black passes into the higher boilng product phase to form an admixture. The admixture is passed to a settling zone where it separates from the liquid. Separation of the carbon black then takes place through the use of a disk centrifuge.
