Minimizing oxygenated aromatic compound content of aqueous solution of reclaimed metal oxidation catalyst |
摘要 |
This invention relates to the reclamation of metal oxidation catalysts by water extraction of a high boiling residual mixture remaining after separation of a benzene di- and/or tricarboxylic acid; e.g., the phthalic acids, trimesic acid or trimellitic acid and reaction solvent, if one is used, from the fluid oxidation effluents produced by the catalytic liquid phase oxidation of a xylene, mesitylene, psendocumene or o-xylene and psendocumene with a source of molecular oxygen in the presence or in the absence of a reaction solvent.
