    Reactive Extraction of Free Organic Acids from the Ammonium Salts Thereof
    摘要:
    该发明涉及一种将有机酸铵盐转化为特定游离有机酸的过程,其中将铵盐的水溶液与有机萃取剂接触,并在水溶液和萃取剂处于液态的温度和压力下解离盐,并引入脱氨介质或夹带气体,以从水溶液中去除NH3并将形成的至少一部分游离有机酸转移到有机萃取剂中。该发明描述了一种改进的释放有机酸的过程,尤其是从铵盐中释放和去除氨并同时用适当的萃取剂从水相中萃取释放的酸,优选为羧酸、磺酸或膦酸,特别是α-羟基羧酸或β-羟基羧酸。这个过程对应于反应性萃取。通过使用脱氨介质或夹带气体(例如氮气、空气、蒸汽或惰性气体,例如氩气),可以显著改善从水溶液中的有机酸铵盐溶液中反应性萃取有机酸的过程。释放的氨由连续气流从水溶液中去除,并可以回馈到生产过程中。游离酸可以通过蒸馏、精馏、结晶、再萃取、色谱、吸附或膜过程等过程从萃取剂中获得。

    The invention relates to a process for converting ammonium salts of organic acids to the particular free organic acid, wherein an aqueous solution of the ammonium salt is contacted with an organic extractant and the salt is dissociated at temperatures and pressures at which the aqueous solution and the extractant are in the liquid state, and a stripping medium or entraining gas is introduced in order to remove NH 3 from the aqueous solution and transfer at least a portion of the free organic acid formed to the organic extractant. The invention described here thus provides an improved process for releasing an organic acid, preferably a carboxylic, sulphonic or phosphonic acid, especially an alpha-hydroxycarboxylic acid or beta-hydroxycarboxylic acid, from the ammonium salt thereof by release and removal of ammonia and simultaneous extraction of the acid released with a suitable extractant from the aqueous phase. This process corresponds to a reactive extraction. The reactive extraction of an organic acid from the aqueous ammonium salt solution thereof can be improved significantly by the use of a stripping medium or entraining gas, for example nitrogen, air, steam or inert gases, for example argon. The ammonia released is removed from the aqueous solution by the continuous gas stream and can be fed back into a production process. The free acid can be obtained from the extractant by a process such as distillation, rectification, crystallization, re-extraction, chromatography, adsorption, or by a membrane process.
