PROCESSES FOR PRODUCING NH4+ -OOC-R-COOH COMPOUNDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COO-NH4+COMPOUNDS AND/OR HOOC-R-COOH COMPOUND ACIDS, AND CONVERSION OF NH4+ -OOC-R-COOH COMPOUNDS TO HOOC-R-COOH COMPOUND ACIDS

A process for making a NH4+ OOC-R-COOH compound from a clarified NH4+ OOC- R-COO' NH4+ compound-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes a NH4+ OOC~R~COOH compound, at least some of a NH4+ QOC-R-COO" NH4+ compound, and at least about 20 wt% water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a NH4+ OOC-R~C00' NH4+ compound-containing liquid portion in contact with a NH4+ OOC-R-COOH compoond-containing solid portion that is substantially free of the NH4+ OOC-R-COO" NH4+compound; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
