摘要： A process for preparing a carboxylic acid of high purity comprises preparing an undersaturated solution of a salt of the carboxylic acid; subjecting the undersaturated salt solution to water-splitting electrodialysis to form base and a supersaturated solution of the carboxylic acid; and, then crystallizing the carboxylic acid from the supersaturated solution. In the preferred embodiment, the undersaturated solution is a fermentation broth containing sodium succinate and the carboxylic acid obtained is succinic acid.

摘要： This invention is directed to methods for recovery of C3-C6 alcohols from dilute aqueous solutions, such as fermentation broths. Such methods provide improved volumetric productivity for the fermentation and allows recovery of the alcohol. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried. Thus, the invention allows for production and recovery of C3-C6 alcohols at low capital and reduced operating costs.

摘要翻译： 本发明涉及从稀释的水溶液如发酵液中回收C3-C6醇的方法。这样的方法提供了用于发酵的改进的体积生产率并允许酒精回收。由于通过同时发酵和回收过程增加了醇产物的有效浓度，所以这种方法还允许在用过的发酵液的生产和干燥中减少能量消耗，这增加了每一批发酵液干燥产生和回收的醇的量。因此，本发明允许以低资本生产和回收C3-C6醇，降低运行成本。

摘要： A process for economically producing highly purified succinic acid comprises growing a succinate-producing microorganism on a low cost carbohydrate substrate; simultaneously neutralizing the fermentation broth and precipitating the succinate as calcium succinate by adding a calcium ion source to form calcium succinate; isolating the calcium succinate; slurrying the calcium succinate in water and treating it with sulfuric acid to form calcium sulfate and succinic acid; and then treating the succinic acid with first a strongly acidic ion exchanger and then a weakly basic ion exchanger to remove impurities and obtain a highly purified succinic acid product. In a preferred embodiment, the calcium succinate is isolated from the fermentation broth by filtration; the filtrate is heated to precipitate additional calcium succinate; and, the spent filtrate which contains nutrients is recycled to the fermentor.
