| Abstract: | The series experiments were carried to develop the optimal technology of synthesizing magnesium aspartate with material of L-aspartate acid and magnesian oxide as materials. The results show that the optimal technology conditions are: the action temperature is 80 ℃,the quality ratio of H_2O/LAA is 3∶1 and mol ratio of LAA/MgO is 1.2∶1. The conditions for crystal are 30 r/min of stiring and 10 ℃ per hour of temperature drop graduation, with output of over 85%. |
