Abstract

PURPOSE: To recover a catalytic metal, by a method wherein a distillation residue in a reaction using a Co and/or Mn catlyst is hydrated and then washed with an org. solvent having a specific dielectic constant.
CONSTITUTION: A distillation residue obtained in a process wherein an aliphatic substituted aromatic hydrocarbon or an oxidized derivative thereof is oxidized in a liquid phase in the presence of a cobalt and/or a manganese catalyst and the formed aromatic carboxylic acid is distilled off from the obtained reaction product is hydrated and then washed with an org. solvent having a specific dielectic constant D of 3.0W3.5 such as acetone or ethyl acetate. By this method, an org. substance such as a tar-like byproduct is removed and cobalt and/or manganese can be recovered. Thus the catalytic metal is recovered simply.
