摘要：
Processes for making monoammonium succinate (MAS) and/or succinic acid (SA) from either a clarified diammonium succinate (DAS)-containing fermentation broth or a clarified MAS-containing fermentation broth include (a) distilling the broth to form an overhead that includes water and optionally ammonia and a liquid bottoms that includes MAS or SA; (b) cooling and/or evaporating the bottoms and optionally adding an antisolvent to the bottoms to attain a temperature and composition sufficient to cause the bottoms to produce a solid portion that contains MAS or SA in contact with a liquid portion; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
