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.

摘要:The present invention relates to processes for producing organic solvents, different monomeric and polymeric chemical substances from fermentable carbohydrate materials (starch, cellulose, hemicellulose), particularly, a lactic acid and its esters, acrylic acid and its esters, propylene glycol, polypropylene, polylactate and polyacrylates, which comprises microbiological fermentation of carbohydrate materials up to a lactic acid and its salts, isolation of lactic acid and its salts, chemical conversion of lactic acid and its salts to organic alcohols aldehydes and ketones, acids, esters, glycols, polymers (i.e. polypropylenes, polylactates and polyacrylates). One or more the steps of the chemical conversion of a lactic acid and its salts carry out joint synthesis of two or more final products.

摘要:The present invention generally relates to novel synthetic methods, systems, kits, salts, and precursors useful in medical imaging. In some embodiments, the present invention provides compositions comprising an imaging agent precursor, which may be formed using the synthetic methods described herein. An imaging agent may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in 18 F. In some cases, an imaging agent including salt forms (e.g., ascorbate salt) may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs.
