Abstract

1. Un procedimiento continuo de desulfatación de una fase orgánica no soluble en agua que contiene ácido fosfórico y ácido sulfúrico, caracterizado por el hecho de que: (a) se trata dicha fase orgánica en una zona de contacto líquido- líquido por medio de una solución acuosa proveniente de la zona de contacto en(c), y se separan luego una fase orgánica y una fase acuosa; (b) se trata la fase orgánica que sale de la zona de contacto en (a) en una segunda zona de contacto por medio de una solución acuosa que contiene iones bario, y luego se separan una fase orgánica y una fase acuosa que contiene un precipitado de BaSO4; (c) se trata la fase orgánica que sale de la zona de contacto en (b) en una tercera zona de contacto por medio de agua, o de una solución acuosa de ácido fosfórico, se separan las fases, se envía de nuevo la fase acuosa a la primera zona de contacto en (a) y se recoge una fase orgánica de ácido fosfórico desulfatado que constituye la producción.
