Abstract

Esta invencion se relaciona con un procedimiento para la preparacion de pigmentos de quinacridona (a) calentando una mezcla de reaccion consistente en (i) unácido 2,5-dianilinotereftálico, un ácido 2,5-dianilino-6,13-dihidrotereftálico o un ácido 2,5-dianilino-3,6-dioxo-1,4-ciclohexadieno-1,4-dic arboxílico; (ii) aproximadamente un 0,1 a aproximadamente un 15 por ciento en peso, en base al componente (a) (i), de uno o más derivados que contienen sulfonilo del ácido 2,5-dianilinotereftálico, del ácido 2,5-dianilino-6,13-dihidrotereftálico y/o del ácido 2,5-dianilino-3,6-dioxo-1,4-ciclohexadieno-1,4-dic arboxílico, y (iii) aproximadamente 3 a aproximadamente 20 partes en peso, por parte de componente (a) (i), de un agente deshidratante (a) (i), de un agente deshidratante, con la condicion de que si alguno de los componentes (a) (i) o (a) (ii) es un ácido 2,5-dianilino-6,13-dihidrotereftálico o derivado del mismo, la etapa de reaccion en una etapa de oxidacion; ahogando la mezcla de reaccion de la etapa (a) con un líquido en el que pigmento de quinacridona es substancialmente insoluble; y aislando el pigmento de quinacridona.
