Abstract
Esta invencion se relaciona con un procedimiento para la preparacion de pigmentos de quinacridona (a) calentando, a una temperatura de desde aproximadamente 80 degree C hasta aproximadamente 145 degree C, una mezcla de reaccion que contiene (1) ácido 2,5-dianilinotereftálico, un éster del ácido 2,5-dianilino-6,13-dihidrotereftálico y/o un derivado de los mismos; (ii) de aproximadamente 3 a aproximadamente 15 partes en peso, por parte de componente (a)(i), de un agente deshidratante, y (iii) de aproximadamente un 0,1 a aproximadamente un 15 por cien en peso, en base al componente (a)(i), de uno o más compuestos policíclicos aromáticos no pigmentarios y/o derivados de los mismos, con la condicion de que, si el componente (a)(i) es éster delácido 2,5-dianilino-6,13-dihidrotereftálico o un derivado del mismo, la etapa de reaccion (a) consiste 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 cual el pigmento de quina-cridona es substancialmente insoluble; (c) aislando el pigmento de quinacridona; (d) eventualmente, acondicionando el pigmento de quinacridona, y (e) eventualmente, mezclando el pigmento resultante con uno o más derivados de quinacridona.
