Abstract

Proceso para la preparación de una sílice precipitada, en la cual se hace reaccionar un silicato con un agente acidificante, a fin de obtener una suspensión de sílice; dicha suspensión de sílice se filtra, a fin de obtener una torta de filtración; y dicha torta de filtración se somete a una operación de licuefacción, opcionalmente en presencia de un compuesto de aluminio; en donde al menos un ácido policarboxílico se agrega a la torta de filtración, durante o después de la operación de licuefacción.Process for the preparation of a precipitated silica, in which a silicate is reacted with an acidifying agent, in order to obtain a silica suspension; said silica suspension is filtered, in order to obtain a filter cake; and said filter cake is subjected to a liquefaction operation, optionally in the presence of an aluminum compound; wherein at least one polycarboxylic acid is added to the filter cake, during or after the liquefaction operation.
