| titleOfInvention | Preparation method of sphericized alpha-DATNBI |
| abstract | The invention discloses a preparation method of sphericized alpha-DATNBI, which comprises the following steps: (1) dissolving DATNBI in a good solvent at a certain temperature to respectively prepare DATNBI solutions with certain concentrations, filtering the DATNBI solutions to remove impurities, and cooling to room temperature to obtain a first reactant; (2) under the condition of stirring, quickly pouring the first reactant into a poor solvent matched with a good solvent for stirring, and stirring to obtain a second reactant; (3) and (3) filtering and draining the second reactant, fully cleaning by adopting the poor solvent used in the step (2), and drying to obtain a finished product. The preparation of the sphericized alpha-DATNBI obviously improves the blocky or acicular appearance of the DATNBI raw material, customizes the crystal form of the DATNBI, makes the DATNBI into a single stable alpha crystal form, and has considerable prospect in the development and application of the DATNBI. |
