一种噁唑烷酮类抗菌药物的晶型B及其制备方法和应用
摘要：
本发明公开了一种噁唑烷酮类抗菌药物的晶型B及其制备方法和应用，所述晶型B在X-射线衍射图谱中包含以下2θ反射角测定的特征峰：8.9±0.2°、14.0±0.2°、17.4±0.2°、18.6±0.2°、22.3±0.2°、25.1±0.2°、26.6±0.2°。该晶型B稳定性好，溶剂残留低，可用于制备药物组合物，在制备抗生素药物中具有重要的应用意义。
摘要（英）：

The invention discloses a crystal form B of oxazolidone antibacterial drugs as well as a preparation method and an application of the crystal form B. In an X-ray diffraction spectrum, the crystal form B comprises characteristic peaks measured by 2 theta reflection angles as follows: 8.9+/-0.2 degrees, 814.0+/-0.2 degrees, 17.4+/-0.2 degrees, 18.6+/-0.2 degrees, 22.3+/-0.2 degrees, 25.1+/-0.2 degrees and 26.6+/-0.2 degrees. The crystal form B is good in stability and low in solvent residue, can be used for preparing drug composition and has great application significance in preparation of antibiotic drugs.
