Abstract
Procedimiento para la purificación de ácido fosforito de procedimiento en húmedo mediante extracción en contracorriente con un disolvente orgánico en el que el agua es limitadamente soluble y que es capaz de recoger el ácido fosfórico, por separación del extracto orgánico de ácido fosfórico respecto del residuo del ácido fosfórico de procedimiento en húmedo no recogido por el disolvente, y por recuperación del ácido fosfórico a partir del extracto orgánico de ácido fosfórico, caracterizado porque se emplea el disolvente con un contenido de agua que es mayor que 0% y menor que 50% de la concentración de saturación del disolvente con agua, y con un contenido de un ácido mineral, que corresponde a la proporción en moles de fosfato fijada a cuestiones en el ácido bruto.
