Abstract
This invention relates to the removal of nickel, iron and copper co-dissolved with cobalt or manganese, or cobalt and manganese in water so that cobalt, manganese, or cobalt and manganese can be precipitated as carbonates and then converted to their acetates sufficiently low in nickel, iron and copper so that said acetates can be recycled to the liquid phase air oxidation of a di- or trimethyl benzene to its corresponding di- or tricarboxylic acid without material inhibition of such oxidation.
