Abstract

Patente de Invenção: <B>"PROCESSO PARA O PREPARO DE SOLUçõES SóLIDAS DE QUINACRIDONA"<D>. Soluções sólidas de quinacridona e 6,13-diidroquinacridona são preparadas através da oxidação de um sal de 6,13-diidroquinacridona finamente dividido em um meio alcóolico básico aquoso usando-se peróxido de hidrogênio como o oxidante. As soluções sólidas são úteis como pigmentos orgânicos vermelhos de elevado desempenho.
