谷氨酸溶液结晶介稳区的性质

Crystallization Metastable Zone Properties of Glutamic Acid Solution

摘要:

测定了谷氨酸在水中的溶解度和超溶解度曲线,并用数学表达式进行拟合,同时还测定了不同降温速率、搅拌转速下的结晶介稳区宽度.结果表明:谷氨酸溶液的溶解度随温度升高而增加,溶液的介稳区随降温速率增加而变宽,随搅拌转速增加而变窄,实验结果与经典成核理论导出的公式基本符合.

Abstract:

In this paper, solubility and supersolubility curves of glutamic acid solution were measured and modeled by mathematical expression. The metastable zone widths of glutamic acid solution at different cooling rate and agitating rate were also measured. The
