| titleOfInvention | Methods for preparation of ammonium salts of c4 diacids by fermentation and integrated methods for making c4 derivatives thereof |
| abstract | Methods for forming ammonium salts of C4 diacids in a fermentation process with removal of divalent metal carbonate salts are disclosed. The pH of fermentation broths for production of C4 diacids is controlled by adding alkaline oxygen containing calcium or magnesium compounds, which forms divalent metal salts of the diacids. The divalent metal salts of the diacids are substituted with ammonium by introduction of ammonium salts at elevated temperature and pressure forming soluble ammonium salts thereof. C02 or bicarbonate is simultaneously added to the fermentation media at the elevated temperature and pressure. Reducing the temperature and pressure forms insoluble divalent metal carbonate salts that are separated from the solubilized ammonium diacid salts. The recovered carbonate salts can be recycled as pH control matelials in subsequent fermentations. The solubilized ammonium diacid salts may form the derivatives N-methyl-2-pyrrolidone (NMP) gamma-butyrolactone (GBL) and 1,4-butane-diol (BDO) in single pot reactions. |
