L-谷氨酸晶种制备新工艺的研究

Study on the new nucleation method about L Glutamic acid

在研究超声波刺激下溶剂及添加剂对谷氨酸（Ｌ－谷氨酸）过饱和溶液成核晶型、粒度的影响的基础上，研究得出一条制取谷氨酸晶种的新工艺。用本法制得的晶种与目前工业上常用的粗晶种相比，具有粒度均匀、晶形完整、纯净（均为α型晶体）的优点。

The effect of ultrasonic.solrent and added impuraty on nuiclei polymorph and granulation of glutamic acid supersaturation solution is fully studied,and based on that,We study and get a new nucleation method.The seeds getted by the method have the advantage of well distributed crystalsize and integrated,parity crystallation (α crystal).
