一种抗肿瘤药物的晶型化合物及其制备方法
摘要：
本发明属于医药技术领域，公开了一种抗肿瘤药物的晶型化合物及其制备方法。该晶型化合物以2θ±0.2°衍射角表示的X‐射线粉末衍射图谱在1.769°、2.997°、4.245°、5.341°、7.121°、7.854°、12.057°、12.937°、15.958°、21.989°、35.161°、36.556°处显示有特征衍射峰，使用Cu‐Kα射线测量得到的X‐射线粉末衍射谱图如图1所示，与现有技术完全不同。本发明还公开了该晶型化合物的制备方法，该制备方法操作简单、温和，适合工业化大生产。
摘要（英）：

The invention belongs to the technical field of medicine, and discloses a crystalline compound for antitumor medicines and a method for preparing the crystalline compound. Characteristic diffraction peaks are displayed at 1.769-degree positions, 2.997-degree positions, 4.245-degree positions, 5.341-degree positions, 7.121-degree positions, 7.854-degree positions, 12.057-degree positions, 12.937-degree positions, 15.958-degree positions, 21.989-degree positions, 35.161-degree positions and 36.556-degree positions of X-ray powder diffraction spectra of the crystalline compound expressed at diffraction angles of 2Theta+/-0.2 degrees, and the X-ray powder diffraction spectra measured by the aid of Cu-K alpha rays are shown as a graph 1 and are totally different from X-ray powder diffraction spectra in the prior art. The crystalline compound and the method have the advantage that the method is easy to implement and suitable for industrial large-scale production and is mild.
