Abstract
Procedimiento para la purificación de ácido fosfórico de procedimiento en húmedo, en que el ácido fosfórico a purificar y un disolvente orgánico, que es parcialmente miscible con agua y es capaz de recoger el ácido fosfórico, son conducidos en contracorriente entre si, la solución orgánica de ácido fosfórico, resultante en tal caso, es separada de las impurezas no recogidas por el disolvente, el producto refinado primario es tratado en contracorriente con un disolvente que contiene ácido mineral, caracterizado porque se mezcla con un disolvente anhidro al extracto orgánico de ácido fosfórico formado en el tratamiento del producto refinado, con un contenido de agua mayor de 0 e igual o menor de 10% en paso, en una proporción ponderal tal que la mezcla obtenida tiene un contenido de agua que es mayor que 0 y menor de 50% de la concentración de saturación con agua en el disolvente, y porque esta mezcla se conduce en contracorriente con respecto al ácido fosforito a purificar.
