Abstract
"GEL DE HIDRóXIDO DE ALUMìNIO". A invenção refere-se a um método para produzir um gel de hidróxido de alumínio estável com base na lixívia de aluminato de sódio é obtida durante a produção de AI~ 2~O~ 3~ de acordo com o método BAYER. A relação molar cáustica (Na~ 2~O~ livre~/AI~ 2~O~ 3~) da lixívia contendo aluminato é ajustada a menos que 1,6. A lixívia é tratada com o anidrido de ácido carboxílico, pelo que o gel de hidróxido de alumínio é precipitado a uma temperatura abaixo de aproximadamente 40<198>C, pelo que o valor de pH está na faixa de 8 a 12. O produto de precipitação e a lixívia são separados um do outro. O produto de precipitação é lavado e secado, pelo que a estrutura amorfa é obtida.
