Abstract

"SOLS BASEADOS EM SìLICA". A presente invenção se refere a um sol baseado em sílica aquoso compreendendo um composto orgânico contendo nitrogênio e partículas baseadas em sílica com uma área de superfície específica de pelo menos 300 metros quadrados por grama de sílica. A presente invenção adicionalmente se refere a um processo para a produção de um sol baseado em sílica aquoso compreendendo um composto orgânico contendo nitrogênio que compreende incorporação de um composto orgânico contendo nitrogênio dentro de um sol baseado em sílica contendo partículas baseadas em sílica com uma área de superfície específica de pelo menos 300 metros quadrados por grama de sílica. A presente invenção também se refere à utilização de um sol baseado em sílica aquoso compreendendo um composto orgânico contendo nitrogênio e partículas baseadas em sílica com uma área de superfície específica de pelo menos 300 metros quadrados por grama de sílica como um agente de floculação na produção de polpa e de papel e na purificação de água. A presente invenção adicionalmente também se refere a um processo para a produção de papel a partir de uma suspensão aquosa contendo fibras celulósicas, e enchimentos opcionais, que compreende adição à suspensão de (i) um sol baseado em sílica aquoso compreendendo um composto orgânico contendo nitrogênio e (ii) pelo menos um polímero orgânico carregado, formando e drenando a suspensão sobre uma tela (peneira).
