Abstract

UNA SOLUCION DE POLIFOSFATO DE METAL ALCALINA ACUOSA CONCENTRADA ES PREPARADA AÑADIENDO ACIDO POLIFOSFORICO QUE TIENE UN ENSAYO DE P SUB 2 O SUB 5 DE APROXIMADAMENTE 82% A 85% EN UNA CANTIDAD DE HIDROXIDO DE METAL ALCALINO ACUOSO CONCENTRADO SUFICIENTE PARA NEUTRALIZAR EL ACIDO. LA SOLUCION DE POLIFOSFATO OBTENIDA ES MAS RICA EN MITADES DE PIROFOSFATO Y TRIPOLIFOSFATO QUE EL ACIDO.
