Abstract
Procedimiento para la obtención de 1,5-y/o 1,8-dinitroantraquinona, prácticamente libre de 1,6-y 1,7-dinitroantraquinona, caracterizado porque se nitra a dinitroantraquinonas la antraquinona y/o 1-nitroantraquino o mezclas de nitración de antraquinona, que contienen antraquinona y/o 1-nitroantraquinona, en ácido nítrico de alta concentración a temperaturas de 0ºC , hasta el punto de ebullición del ácido nítrico, y a continuación directamente de la mezcla de reacción, mediante ajuste de una fracción molar de ácido nítrico de HNO3=0,90 hasta 0,68 con relaciones molares entre ácido nítrico y dinitroantraquinona de 10: 1 hasta 80:1 se precipita directamente la 1,5-dinitroantraquinona y se aisla en forma usual , a continuación del filtrado, mediante ajuste de una fracción molar de ácido nítrico HNO3=0,80 hasta 0,50 con relaciones molares entre ácido nítrico y dinitroantraquinonas disueltas de 10:1 hasta 80:1 se precipita la 1,8-dinitroantraquinona y se aisla en forma usual, o directamente después de la nitración, mediante ajuste de una fracción molar de ácido nítrico de HNO3=0,80 hasta 0,50 en relaciones molares entre ácido nítrico y dinitroantraquinonas de 10:1 hasta 80:1, se precipitan conjuntamente la 1,5 y 1,8-dinitroantraquinona y se aisla en forma habitual.
