Abstract
La invención es concerniente con un método para la preparación de sílice precipitada en el cual: (i) un arrancador, que tiene un pH de 2 a 5 es preparado; (ii) un silicato y ácido son agregados simultáneamente al arrancador, de tal manera que el pH del medio de reacción es de entre 2 y 5; (iii) un silicato es agregado hasta que se alcanza un pH de 7 a 10; (iv) un silicato y ácido son agregados simultáneamente, de tal manera que el pH es de entre 7 y 10; (v) se agrega un ácido hasta que se alcanza un pH de 2.5 a 5.3 y (vi) el medio de reacción es puesto en contacto con un ácido y silicato, de tal manera que el pH es de entre 2.5 y 5.3, en donde el ácido usado en por lo menos una de las etapas del método es un ácido concentrado.
