摘要： The present invention is directed to a method for the production of D,L-aspartic acid. The method comprises reacting an unsaturated dicarboxylic acid or anhydride, such as, maleic acid, fumaric acid, maleic anhydride, or mixtures thereof, with excess aqueous ammonia at an elevated temperature and pressure for a time sufficient to produce diammonium D,L-aspartate. The produced diammonium D,L-aspartate is then neutralized to D,L-aspartic acid. Excess unreacted ammonia and various by-products may be recycled and re-used in the method, thereby minimizing waste and reducing cost. The produced D,L-aspartic acid may be subsequently used to make polyaspartic acid.

摘要： Polysuccinimide is prepared by reacting ammonia gas with liquid maleic anhydride. The reaction is initially carried out at a temperature which is above the melting point of the maleic anhydride but below the boiling point of liquid maleic anhydride for a time period sufficient for the liquid maleic anhydride to react with the ammonia gas to form a reaction product thereof. The reaction product is subsequently polymerized to polysuccinimide. The present method avoids the prior art problems of water removal and minimizes the need for ammonia handling equipment. The polysuccinimide product can be readily hydrolyzed to polyaspartic acid or a salt thereof, if desired.
摘要翻译：聚氨基琥珀酰亚胺通过氨气与液体马来酸酐反应制备。反应最初在高于马来酸酐的熔点但低于液体马来酐的沸点的温度下进行足够长的时间，以使液体马来酸酐与氨气反应形成其反应产物。反应产物随后聚合成聚琥珀酰亚胺。本方法避免了现有技术的除水问题，并最大限度地减少了对氨处理设备的需求。如果需要，聚琥珀酰亚胺产物可以容易地水解成聚天冬氨酸或其盐。
