摘要 |
<p>An improved method of recovering a palladium catalyst from a liquid reaction mixture having been produced by oxidative coupling reaction of an aromatic compound in the presence of a catalyst containing palladium(II) salt is disclosed. The improved method comprises heating the liquid reaction mixture under stirring at a temperature of 180 DEG to 280 DEG C. in an atmosphere containing hydrogen gas at a partial pressure of 5 to 60 kg/cm2 whereby reducing the catalyst in the reaction mixture and precipitating a metallic palladium from the reaction mixture.</p> |
