Recovery of metal components of a catalyst in a process for production of trimellitic acid |
摘要 |
A process for recovering cobalt and manganese components from a product stream or a residue stream that resulted from a process which employs a catalyst system containing the cobalt and manganese components for oxidizing pseudocumene to trimellitic acid includes the steps of adding a precipitating agent to the product stream or the residue stream in an effective amount to react with the cobalt and manganese components in the product stream or the residue stream.
