摘要： A process for the production and isolation of lactic acid is provided. A lactate feed solution, preferably obtained from a fermentation broth is combined with and extracted by a water-immiscible base in the presence of an acidifying agent. Lactic acid is recovered from the resulting organic phase. Recovered carbonate or bicarbonate from the aqueous phase can be recycled to the fermentor and regenerated extractant can be recycled for use in the extraction.

摘要： In the production of citric acid aqueous mother liquor originating from a lime/sulfuric acid process is subjected to a multi-stage counter-current extraction with an amine based organic extractant. A solution of a further amount of citric acid derived from direct extraction of a citric acid fermentation broth is judicously injected into the organic phase stream in the counter-current extraction and a combined extract is withdrawn from the operation. This extract can be subjected to any known treatment for the recovery of citric acid values.

摘要： A process is disclosed for purifying an aqueous feed stream comprising a product organic acid, such as lactic acid, and a strong contaminant, such as pyruvic acid or oxalic acid. The molar concentration of the product organic acid in the feed stream typically is at least 20 times greater than the molar concentration of the strong contaminant. The aqueous feed stream is contacted with a first immiscible basic extractant that has at least a 3-fold greater affinity for the strong contaminant than for the product organic acid. The majority of the strong contaminant and some product organic acid become complexed with the first immiscible basic extractant. The complexed first immiscible basic extractant is separated from the aqueous stream, thereby producing a first effluent stream that comprises product organic acid and that has a greater ratio of molar product organic acid to molar strong contaminant than the aqueous feed stream did. The complexed first immiscible basic extractant is contacted with a displacing acid. The first immiscible basic extractant has a greater affinity for the displacing acid than it does for the strong contaminant or the product organic acid, and as a result, product organic acid and strong contaminant are displaced over a period of time from the complexed first immiscible basic extractant, producing a second effluent stream that comprises a major amount of product organic acid and a third effluent stream that comprises a major amount of strong contaminant.
摘要翻译：公开了用于纯化包含产物有机酸如乳酸和强烈污染物如丙酮酸或草酸的含水进料流的方法。进料流中产物有机酸的摩尔浓度通常比强污染物的摩尔浓度大至少20倍。含水进料流与第一不混溶碱性萃取剂接触，对于强污染物的亲和力比产物有机酸具有至少3倍的亲和力。大部分强烈的污染物和一些产品的有机酸与第一个不混溶的碱性萃取剂复合。将复合的第一不混溶的碱性萃取剂与水流分离，从而产生包含产物有机酸的第一流出物流，并且与含水进料流具有更大的摩尔产物有机酸与摩尔强的污染物的比例。复合的第一不混溶碱性萃取剂与置换酸接触。第一种不混溶的碱性萃取剂对于排出酸的亲和力高于对强的污染物或产品有机酸的亲和性，结果产物有机酸和强的污染物在一段时间内从复合的第一不溶混碱产生包含大量产物有机酸的第二流出物流和包含主要量的强污染物的第三流出物流。
