Abstract

"PROCESSO DE OXIDAçãO PARA PREPARAçãO DE PIGMENTOS DE QUINACRIDONA". A presente invenção refere-se a um processo de preparação de quinacridona por oxidação de um sal de 6,13-diidroquinacridona correspondente ao pigmento de quinacridona com peróxido de hidrogênio como agente oxidante na presença de ácido 2,7-antraquinona dissulfónico como catalisador. O processo da invenção é económico e ambientalmente favorável e produz pigmentos de quinacridona de alto desempenho e alto rendimento.
