Изобретение относитс к новому способу получени йодистого бетаина, который может быть использован в медицине в качестве химических реактивов и исходного сырь дл органического синтеза.The invention relates to a new process for the production of betaine iodide, which can be used in medicine as chemical reagents and as a raw material for organic synthesis.
Известен способ получени йодистого бетаина алкилированием аминокислоты в избытке йодистого метила 1.A known method for producing betaine iodide by alkylation of an amino acid in an excess of methyl iodide 1.
Недостатком известного снособа вл етс использование в процессе довитого йодистого метила.A disadvantage of the known removal method is the use of methyl iodide in the process.
Цель изобретени - улучшение условий труда за счет исключени из процесса довитого исходного продукта.The purpose of the invention is to improve working conditions by eliminating from the process the finished source product.
Поставленна цель достигаетс предлагаемым способом получепи йодистого бетаина взаимодействием гидрата бетаина с йодистым аммонием при мольном соотношении 1 : 1 при 60-70°С в водно-спиртовой среде. Процесс протекает 20-40 мин. Целевой нродукт нолучают с выходом 88-95%.The goal is achieved by the proposed method for obtaining a betaine iodide by reacting betaine hydrate with ammonium iodide at a molar ratio of 1: 1 at 60-70 ° C in an aqueous-alcoholic medium. The process takes 20-40 minutes. The target product is obtained with a yield of 88-95%.
Пример. К 20 мл спиртового раствора, содержащего 4,41 г бетаина добавл ют 4,73 гExample. To a 20 ml alcohol solution containing 4.41 g of betaine was added 4.73 g
йодистого аммони (насыщенный водный раствор ). Смесь нагревают при 60-70°С в течение 30 мин. Спирт и выдел юшийс аммиак отгон ют под вакуумом, после чего смесь охлаждают . Получают йодистый бетаин, выход 88-95%.ammonium iodide (saturated aqueous solution). The mixture is heated at 60-70 ° C for 30 minutes. The alcohol and liberated ammonia is distilled off under vacuum, after which the mixture is cooled. Betaine iodide is obtained, yield 88-95%.
