一种盐酸羟哌吡酮新晶型及其制备方法
摘要：
本发明涉及盐酸羟哌吡酮一种新的晶型以及其制备方法。所述的盐酸羟哌吡酮新晶型命名为晶型Ⅲ，其X射线粉末衍射图谱中的2θ角在11.8°，14.4°，15.7°，18.7°，19.4°，26.2°，28.8°处有特征峰。本发明所获得的盐酸羟哌吡酮晶型Ⅲ纯度高、稳定性好，非常适用于工业化生产。
摘要（英）：

The invention relates to a hipydone hydrochloride new crystal form and a preparation method thereof. The hipydone hydrochloride new crystal form is named as crystal form III, and characteristic peaksexist when a 2 theta angle in an X-ray powder diffraction pattern of the hipydone hydrochloride new crystal is 11.8 degrees, 14.4 degrees, 15.7 degrees, 18.7 degrees, 19.4 degrees, 26.2 degrees and 28.8 degrees. The obtained hipydone hydrochloride crystal form III has the high purity and good stability and is very suitable for industrial production.
