Abstract
Procedimiento para la preparación de soluciones alcohólicas de ácido fosfórico a partir de fosfatos ácidos o sus mezclas en presencia de agua y de un ácido mineral fuerte, por extracción con alcoholes, caracterizado porque una solución o suspensión acuosa de los fosfatos es conducida en contracorriente con respecto a una mezcla de un alcohol con 3 a 8 átomos de carbono o a una mezcla de dichos alcoholes y de un ácido mineral fuerte, empleándose el alcohol o la mezcla de alcoholes en una proporción en volumen con respecto a solución o suspensión de fosfatos de 2:1 hasta 20:1 y empleándose el ácido mineral en una cantidad que es justamente suficiente para formar casi de modo cuantitativo ácido fosfórico a partir de los fosfatos y escogiéndose los contenidos de agua del alcohol o de la mezcla de alcoholes, del ácido mineral y de la solución o suspensión de fosfatos de modo tal que después del mezclado de estos componentes resulte una fase de sales capaz de fluir, separada de la fase alcohólica, la cual fase de sales es separada de la fase alcohólica.
