| description | The present disclosure provides a process for recovering and recycling a catalyst from the mother liquor generated during the production of aromatic carboxylic acids. The process comprises treating the mother liquor with an alkyl aromatic compound and further treating the first aqueous layer obtained with an ionic liquid to obtain a catalyst rich aqueous mixture. The catalyst rich aqueous mixture is recycled to the oxidation reactor.
La presente divulgación proporciona un proceso de recuperación y reciclado de un catalizador a partir de un licor madre generado durante la producción de ácidos carboxílicos aromáticos. El proceso incluye el tratamiento del licor madre con un compuesto aromático alquilo y, posteriormente, el tratamiento de la primera capa acuosa obtenida con un líquido iónico para obtener una mezcla acuosa rica en catalizador. La mezcla acuosa rica en catalizador se recicla en el reactor de oxidación. |
