Abstract

"PROCESSO PARA PREPARAçãO DE UM áCIDO SILìCICO DE PRECIPITAçãO HIDRóFOBO COM ELEVADO GRAU DE BRANCURA, E ABSORçãO DE UMIDADE EXTREMAMENTE BAIXA". A invenção refere-se a um processo para preparação de ácidos silícicos de precipitação hidrófobos, caracterizado pelo fato de que a) é preparada uma mistura de um derivado de organossiloxano e um ácido silícico de precipitação, b) é realizado um condicionamento a 10 até 150<198>C por um tempo de 0,5 até 72 horas e C) é realizada uma têmpera oxidativa sob condições líquidas acima de 300<198>C com um gás oxidante. As condições fluidas são ajustadas de preferência em um leito em suspensão, leito fixo, leito turbilhonado, leito fluido e/ou leito em ebulição.
