    • Novel crystalline forms of and a process for converting perylene-3, 4:9, 10-tetracarboximide of the general formula I to a form used as a fluorescent dye. The process including: a) dissolving or suspending the perylene-3, 4:9, 10-tetracarboximide in a solvent to obtain a solution or suspension; and b1) cooling the solution obtained in step a) to a temperature at or below the crystallization temperature of the perylene-3, 4:9, 10-tetracarboximide and, if the solvent is organic, removing excess solvent until the first crystals form, otherwise, adding water or dilute aqueous solutions of the solvent until the first crystals form, and maintaining the solution at that temperature for further crystallization; or b2) cooling the suspension obtained in step a) to or below the crystallization temperature when the temperature in step a) was above the crystallization temperature, and maintaining the suspension at the temperature for further crystallization to form one or more solvate crystals.
    • 将通式I的苝-3,4:9,10-四甲酰亚胺转化成用作荧光染料的形式的新型结晶形式和方法。 该方法包括:a)将苝-3,4:9,10-四甲酰亚胺溶解或悬浮在溶剂中以获得溶液或悬浮液; 和b1)将步骤a)中获得的溶液冷却至等于或低于苝-3,4:9,10-四甲酰亚胺的结晶温度的温度,如果溶剂是有机的,则除去多余的溶剂直到形成第一晶体, 否则,加入水或稀释的溶剂水溶液直到形成第一晶体,并将溶液保持在该温度下进一步结晶; 或b2)当步骤a)中的温度高于结晶温度时,将步骤a)中获得的悬浮液冷却至或低于结晶温度,并将悬浮液保持在该温度下进一步结晶以形成一种或多种溶剂化物晶体。
