    • 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.
    • 公开了在除去二价金属碳酸盐的发酵过程中形成C4二酸铵盐的方法。 用于生产C4二酸的发酵液的pH值通过加入形成二酸的二价金属盐的含钙或镁化合物的碱性氧来控制。 二元酸的二价金属盐通过在升高的温度下引入铵盐和压力形成其可溶性铵盐而被铵取代。 在升高的温度和压力下,将CO 2或碳酸氢盐同时加入到发酵培养基中。 降低温度和压力形成不溶性二价金属碳酸盐,其与可溶性二铵酸盐分离。 回收的碳酸盐可以在随后的发酵中作为pH控制物质再循环。 可溶性二铵酸盐可在单锅反应中形成N-甲基-2-吡咯烷酮(NMP)γ-丁内酯(GBL)和1,4-丁烷二醇(BDO)的衍生物。
