Versuchsvorschrift

79 Parts of methanol and 12 parts of a 50% NaOH aqeuous solution were fully stirred in a flask of stainless steel. 10 Parts of the 6,13-dihydroquinacridone obtained in Example 9 and 10 parts of sodium m-nitrobenzenesulfonate were gradually added, and the mixture was refluxed at 70° to 75° C. for 3 to 5 hours. The mixture was cooled until it had a temperature of 40° C. or lower, and the mixture was filtered. The resultant cake was washed with hot water until the wash water was colorless and transparent, and dried, to give 9.78 parts (98.4% of the theoretical yield) of an unsubstituted quinacridone. The quinacridone was measured for a purity by IR and absorbance to show 99.2% of quinacridone and 0.8% of 6,13-dihydroquinacridone. The quinacridone had a specific surface area of 22.8 m2 /g.
