Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UN TRIOFOSFATO SODICO GRANULAR. SE SECA POR ATOMIZACION UNA SOLUCION O SUSPENSION DE ORTOFOSFATO SODICO, QUE TIENE UNA PROPORCION EN MOLES DE NA O:P O , QUE CORRESPONDE A LA DEL TRIOFOSFATO SODICO, EN UNA TORRE CALENTADA CON AYUDA DE UNA BOQUILLA, REALIZANDOSE CONDENSACION DEL ORTOFOSFATO. CONJUNTAMENTE CON EL ORTOFOSFATO SE ATOMIZA UNA SOLUCION DE UN FOSFATO DE SODIO, POTASIO O AMONIO DE ELEVADO PESO MOLECULAR, CON CONTENIDOS DE P O COMPRENDIDOS ENTRE 60 Y 73% EN PESO.
