| description | The invention belongs to the field of medicines, and particularly relates to a purification method for chlorin e6 . The purification method comprises the following steps: addition of alkali for salt formation and addition of acid for dissociation. The purification method comprises the following specific steps: namely dissolving a crude chlorin e6 product into a salt-forming solvent, adding alkalito form salt, conducting crystallizing and filtering, then dissolving a filter cake into a dissociation solvent, adding acid for dissociation, and performing crystallizing to obtain high-purity chlorin e6. The method has the advantages of simple and stable process operation and high purification efficiency.
本发明属于医药领域，具体而言涉及一种二氢卟吩e6的纯化方法。该纯化方法包括加碱成盐和加酸解离的步骤，即将二氢卟吩e6粗品溶于成盐溶剂中，加入碱成盐，析晶过滤，然后将滤饼溶于解离溶剂中，加入酸解离，析晶后得到高纯度二氢卟吩e6。该方法具有工艺操作简单稳定、提纯效率高的优点。 |
