Abstract

Se revela un proceso que se refiere a la recuperacion de un catalizador metálico de una corriente de purga oxidante producida en la síntesis de ácido carboxílico, típicamente tereftálico. En particular, el proceso involucra la recuperacion de un catalizador metálico de una corriente de purga oxidante mediante la utilizacion de un filtro por presion, la combinacion de agua con un líquido madre para recuperar el catalizador metálico y después someter una mezcla acuosa así formada a una extraccion de una unica etapa con un solvente de extraccion para producir una corriente de extracto que comprende impurezas orgánicas y una corriente de rafinato que comprende el catalizador metálico.
