摘要:
为了探究不同溶剂体系对磷酸奥司他韦的晶体生长的影响,通过构建修正附着能模型计算了磷酸奥司他韦在真空、丙酮和乙腈环境下的晶体形态,同时在相应的溶剂环境下进行重结晶实验,并采用X射线粉末衍射仪、扫描电子显微镜以及颗粒和粉体特征分析仪表征结晶产物的晶体结构,微观形貌以及粉体性能。结果表明:在真空条件下决定磷酸奥司他韦晶习的优势晶面为(1 1 0)和(0 0 1),附着能分别为-42.49 kcal/mol和-127.27 kcal/mol;磷酸奥司他韦在不同溶剂条件下的晶习变化有明显差异,晶习均为矩形棱柱,在丙酮中的晶习长径比大于乙腈中的晶习长径比,预测晶习与实验结果吻合较好;在乙腈中重结晶的晶体产物的休止角为32.8°,压缩度为37.4%,表明流动性较好。该研究表明通过修正附着能模型可以预测溶剂对晶体生长及其形态的影响,可在工业生产中为磷酸奥司他韦的晶习调控与溶剂的选择提供理论支持。
