More Information
Summary:The invention provides a method for obtaining granular D-aspartic acid, which is characterized in that the crystal form of D-aspartic acid is changed by cooperatively controlling the pH and temperature of a system to obtain the granular D-aspartic acid. Granular D-aspartic acid can be obtained through the method, the centrifugal moisture of the D-aspartic acid wet material is remarkably reduced, and the quality of the crude wet material is improved. 本发明提供一种获得颗粒状D-天冬氨酸的方法，通过协同控制体系pH和温度来改变D-天冬氨酸的晶型，得到颗粒状的D-天冬氨酸。通过本发明方法能够得到颗粒状的D-天冬氨酸，显著减少D-天冬氨酸湿料的离心水分，提高粗品湿料品质。
