摘要
采用冷却、溶析、等电点、真空蒸发结晶方法对L-谷氨酰胺进行重结晶,利用检测显微镜分析所得结晶产品的粒度分布及晶形,结合重结晶收率,最终确定了L-谷氨酰胺冷却-溶析结晶方法为制备L-谷氨酰胺产品的最优方法。
L-Glutamine was recrystallized by solventing-out,cooling,isoelectric point and vacuum evaporation crystallization method.Particle size and morphology were observed under electron microscope.The crystallization process of solventing-out and cooling was determined.
