Abstract

PROCEDIMIENTO PARA LA OBTENCION DE HIDROGENOFOSFATO CALCICO. COMPRENDE LA REACCION DE ACIDO FOSFORICO PURO CON UNA SUSPENSION ACUOSA DE CARBONATO CALCICO; SEGUIDA DE LA SEPARACION DEL HIDROGENOFOSFATO CALCICO FORMADO POR FILTRACION Y SECADO. EL CARBONATO CALCICO EMPLEADO SE OBTIENE POR TRATAMIENTO DE UNA SUSPENSION ACUOSA DE HIDROXIDO CALCICO IMPURO CON UNA SAL AMONICA O DE UNA AMINA, FILTRACION, CLARIFICACION CON CARBON ACTIVO Y REACCION CON DIOXIDO DE CARBONO PARA FORMAR CARBONATO CALCICO, QUE SE SEPARA DE LAS AGUAS MADRES, SE LAVA Y SE SUSPENDE EN AGUA.
