Abstract

Esta invencion se relaciona con un procedimiento para la preparacion de pigmentos de quinacridona (a) calentando, a una temperatura de aproximadamente 80 degree C a aproximadamente 145 degree C, una mezcla de reaccion que contiene (i) ácido 2,5-dianilinotereftálico, un éster del ácido 2,5-dianilino-6,13-dihidrotereftálico y/o un derivado del mismo; (ii) aproximadamente 3 a aproximadamente 15 partes en peso, por parte de componente (a) (i), de un agente deshidratante, y (iii) aproximadamente un 0,1 a aproximadamente un 15 por ciento en peso, en base al componente (a) (i), de uno o más pigmentos de quinacridonicos, con la condicion de que, si el componente (a) (i) es un éster del ácido-2,5-dianili no 6,13-dihidrotereftálico o un derivado del mismo, la etapa de reaccion (a) consista adicionalmente en una etapa de oxidacion; (b) ahogando la mezcla de reaccion de la etapa (a) por adicion de dicha mezcla de reaccion a aproximadamente 3 hasta aproximadamente 15 partes en peso, por parte de componente (a) (i), de un líquido en el que el pigmento de quinacridona es substancialmente insoluble; (c) aislando el pigmento de quinacridona; (d) acondicionando eventualmente el pigmento de quinacridona, y (e) mezclando eventualmente el pigmento resultante con uno o más derivados de quinacridona.
