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
摘要
<p>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 compound-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.</p>
