Abstract
Es un proceso para tratar soluciones catalizadoras de las reacciones de carbonilación, de bajo contenido de agua y que contienen un componente rodio yun componente de metales, para eliminar los productos de corrosión metálica. El procesoconsiste en poner en contacto la solución catalizadora con una resinade intercambio de iones, preferentemente en forma litio, y una cantidad suficiente de agua para disminuir las concentraciones de los iones de metalesalcalinos y optimizarla elimina ción de contaminantes provenientes de la corrosión.
