| 摘 要： | 为考察溶析结晶纯化去乙酰真菌环氧乙酯的效果,研究了不同的溶剂、反溶剂含量和导入方式对去乙酰真菌环氧乙酯结晶的影响.在静态结晶实验的基础上,通过设计正交实验L9(34)研究动态结晶过程中各因素对去乙酰真菌环氧乙酯收率和纯度的影响.结果表明:有效地控制反溶剂含量及其导入方式可以提高晶体的纯度和收率并影响晶体的形态.去乙酰真菌环氧乙酯动态结晶最佳条件:结晶温度为15℃,溶剂-反溶剂体积比(丙酮-水)为2∶3,反溶剂流加时间为3 h.

| Abstract: | In order to purify deacetylmycoepoxydiene(DAM)using solventing-out crystallization technique,the optimal conditions of crystallization were investigated by orthogonal design,and the recovery and purity of DAM were used as major evaluating contents.The results showed that the shapes of DAM crystal were influenced by different solvents,the recovery and purity of DAM were also influenced by the volume of anti-solvent and the way it was conducted.The optimal parameters are described as follows:crystallization t... |
