    • Novel crystal forms of solid solutions of 2,9-dimethyoxyquinacridone and 2,9-dichloroquinacridone. The crystal forms may be formed by a process comprising the steps of: a) heating a mixture of 2,5-di(4-methoxyanilino)terephthalic acid, and 2,5-di(4-chloroanilino)terephthalic acid in polyphorsphoric acid at a temperature less than 1050 C to form a mixture of 2,9-dimethoxyquinacridone and 2,9-dichloroquinacridone; b) combining the mixture of 2,9-dimethoxyquinacridone and 2,9-dichloroquinacridone with water; and c) heating the mixture of 2,9-dimethoxyquinacridone and 2,9-dichloroquinacridone at a temperature not more than 110° C. Another crystal form may be formed by the process of heating a mixture of 2,9-dimethoxyquinacridone and 2,9-dichloroquinacridone in a polar aprotic solvent. These products are may be used for coloring fibers, plastics, paints, coatings, printing inks, color filters, cosmetics, automotive coatings, textiles, fibers, powder coatings, in-mold coatings, laminate films, and the like.
    • 2,9-二甲氧基喹吖啶酮和2,9-二氯喹吖啶酮的固体溶液的新型晶体形式。 晶体形式可以通过包括以下步骤的方法形成:a)在多晶磷酸中加热2,5-二(4-甲氧基苯胺基)对苯二甲酸和2,5-二(4-氯苯胺基)对苯二甲酸的混合物 温度低于1050℃以形成2,9-二甲氧基喹吖啶酮和2,9-二氯喹吖啶酮的混合物; b)将2,9-二甲氧基喹吖啶酮和2,9-二氯喹吖啶酮的混合物与水混合; 和c)在不高于110℃的温度下加热2,9-二甲氧基喹吖啶酮和2,9-二氯喹吖啶酮的混合物。另外一种晶形可以通过加热2,9-二甲氧基喹吖啶酮和2,9-二甲氧基喹吖啶酮的混合物, 9-二氯喹吖啶酮在极性非质子溶剂中。 这些产品可用于着色纤维,塑料,油漆,涂料,印刷油墨,滤色器,化妆品,汽车涂料,纺织品,纤维,粉末涂料,模内涂料,层压膜等。
