PROCESSES FOR PRODUCING ADIPIC ACID FROM FERMENTATION BROTHS CONTAINING DIAMMONIUM ADIPATE
Processes for making AA from either a clarified DAA-containing fermentation broth or a clarified MAA-containing fermentation broth that include distilling the broth under super atmospheric pressure at a temperature of >100° C. to about 300° C. to form an overhead that comprises water and ammonia, and a liquid bottoms that includes AA, and at least about 20 wt % water; cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a liquid portion and a solid portion that is substantially pure AA; and separating the solid portion from the liquid portion. A method also reduces the broth distillation temperature and pressure by adding an ammonia separating and/or water azeotroping solvent to the broth.
