Abstract

La presente invencion se refiere a un procedimiento para la preparacion de pigmentos de quinacridona que comprende a) calentar, a una temperatura de aproximadamente 80 grados C a aproximadamente 145 grados C, una mezcla de reaccion que comprende i) ácido 2,5-dianilinotereftálico o un derivado del ácido 2,5-dianilinotereftálico que tiene uno o más sustituyentes en al menos un anillo de anilina, ii) 2 a 10 partes en peso, con respecto al componente (a) (i), de un agente deshidratante, y iii) 0,01 a 10 por ciento en peso, con respecto al componente (a) (i), de una sal distinta a una sal de hierro; b) anegar de la mezcla de reaccion procedente de la etapa (a) añadiendo dicha mezcla de reaccion a 3 a 15 partes en peso, con respecto al componente (a) (i), de un líquido en el que el pigmento es sustancialmente insoluble; c) aislar el pigmento de quinacridona; y d) opcionalmente, acondicionar el pigmento de quinacridona.
