Reaction Steps
Quinacridone (50 grams) was dispersed in water (1000 grams) and potassium hydroxide (50 grams) was added. The resulting slurry was then heated to 65° C. and sodium peroxydisulfate (200 grams) was added over a 6 hour period. The resulting slurry was stirred continuously for 8 hours at 65° C. then filtered. The resulting presscake was washed with water to neutral and dried. 55 grams of bright yellow highly pure quinacridonequinone was produced.
