Claims (5)
1. Способ получения в чистом виде кристаллической формы 1 полиморфного кристаллического торсемида, при котором торсемид растворяют в смеси этанола с водой при нагревании, затем охлаждают и после отделения кристаллов сушат, отличающийся тем, что сушку проводят с одновременной механической нагрузкой на кристаллы, например, в лопастной сушилке, причем кристаллы кристаллической формы 2 переходят в кристаллическую форму 1.
2. Способ по п.1, отличающийся тем, что перед кристаллизацией проводят механическое отделение твердых веществ, в частности, фильтрованием.
3. Способ по п.1 или 2, отличающийся тем, что этанол и воду вводят в массовом соотношении 55:46 (объемном отношении примерно 60:40) с максимальным отклонением каждой доли 15 мас.%.
4. Способ по п.1, отличающийся тем, что для получения чистой кристаллической формы 2 охлаждение проводят с перепадом температур от 0,2 до 1°С/мин, предпочтительно от 0,4°/мин до 0,6°/мин, до температуры ниже 40°С.
5. Способ по п.1, отличающийся тем, что для получения чистой кристаллической формы 2 торсемида непосредственно перед или при достижении температуры насыщения, в частности, при от 70° до 60°С, при охлаждении раствора вводят затравочный кристалл кристаллической формы 2.
