Abstract

Patente de Invenção: <B>"GRâNULOS DE SìLICA PRECIPITADA"<D>. Grânulos de sílica precipitada com as propriedades de poeira: máximo de poeira <243> 5,0% em peso índice de poeira <243> 10,0% em peso índice de deposição até 5% <243> 5 índice de deposição até 2% <243> 50 são preparados por ajuste de uma suspensão de sílica precipitada para um pH de 2 a 3,9, e secagem por pulverização. Eles são usados para adsorção de substâncias ativas líquidas tais como, por exemplo, solução de cloreto de colina e vitamina E.
