Abstract
PROCEDIMIENTO PARA LA PRODUCCION DE POLIFOSFATOS DE AMONIO. EL PROCEDIMIENTO CONSISTE EN HACER REACCIONAR EL AMONIO GASEOSO CON EL ACIDO FOSFORICO SELECCIONADO ENTRE EL ACIDO ORTOFOSFORICO Y EL SUPERFOSFORICO. EL EMPLEO DE UNO U OTRO DEPENDE DE LA CONVERSION A LAS FORMAS CONDENSADAS QUE SE DESEE ALCANZAR. CON EL ACIDO SUPERFOSFORICO ES POSIBLE ALCANZAR UNA CONVERSION SUPERIOR AL 80 POR 100. EL ACIDO ORTOFOSFORICO EMPLEADO TIENE UNA CONCENTRACION DE P2O5 DEL 57 AL 60 POR 100 EN PESO. EL APARATO EMPLEADO CONSTA DE UNA PEQUEÑA CAMARA CILINDRICA, CON EJE VERTICAL DEL CILINDRO. DICHA CAMARA TERMINA EN SU PARTE INFERIOR, Y GRADUALMENTE, EN UNA SECCION ESTRECHADA.
