    摘要: A process for producing a new crystalline polymorphic form of flavanthrone is disclosed which comprises treating crude flavanthrone with nitric acid. This new form exhibits only one prominent X-ray diffraction peak between 7.00 and 8.00 dA and only two prominent peaks between 3.30 and 3.75 dA. In contrast to the known form of flavanthrone, the new form exhibits desirable transparent mass tones when employed as a pigment.
