ABSTRACT:
This invention relates to a process of treating hydrated chromium oxides with aqueous base(s) in the presence of dispersing agent(s) to form upon dehydration a virtually sediment-free oil solution and/or dispersion of hydrated chromium oxide in amounts up to about 20% chromium content. The product formed is a stable, bright, fluid oil-soluble and/or oil-dispersible hydrated chromium oxide upon filtration or centrifugation to remove minimal sediment.
