阅读说明：本技术 制备氨基苯甲酸或氨基苯甲酸反应产物的方法 (Process for preparing aminobenzoic acid or aminobenzoic acid reaction products ) 是由 W·克勒克纳 F·贝格尔 G·耶格尔 S·克拉夫尔 G·奥夫 于 2019-06-05 设计创作，主要内容包括：本发明涉及使用发酵法制备氨基苯甲酸或氨基苯甲酸反应产物的方法,其中(I)在通过发酵获得的发酵液中形成的氨基苯甲酸部分地,任选由于溶解平衡而尽可能地,结合为不溶性氨基苯甲酸钙,所述不溶性氨基苯甲酸钙然后(II)独自地或作为与发酵中所用的微生物的混合物分离出来,并转化成水溶性形式并析出不同于氨基苯甲酸钙的不溶性钙盐,然后(III)通过将二氧化碳在压力下引入已脱除沉淀钙盐的水溶液而使氨基苯甲酸沉淀。(The invention relates to a method for producing aminobenzoic acid or aminobenzoic acid reaction products using a fermentation process, wherein (I) aminobenzoic acid formed in a fermentation broth obtained by fermentation is partially, optionally as far as possible due to the solubility equilibrium, bound as insoluble calcium aminobenzoate, which is then (II) isolated alone or as a mixture with microorganisms used in the fermentation and converted into a water-soluble form and an insoluble calcium salt different from the calcium aminobenzoate is precipitated, and then (III) aminobenzoic acid is precipitated by introducing carbon dioxide under pressure into an aqueous solution from which the precipitated calcium salt has been removed.)
