| titleOfInvention | Process for crystallizing enantiomerically enriched 2-acetylthio-3-phenylpropionic acid |
| abstract | Process for crystallizing 2-acetylthio-3-phenylpropionic acid from a solution of acetylthiophenylpropionic acid, wherein, at a temperature lower than 50° C., an antisolvent is added to form a mixture of antisolvent and acetylthiophenylpropionic acid solution; wherein seed crystals are added to the mixture before crystallisation occurs; and wherein the antisolvent is dosed over time during the occurrence of crystallisation. n Preferably, the crude reaction mixture obtained in the preparation of the acetylthiophenylpropionic acid is applied as acetylthiophenylpropionic acid-containing medium. n Preferably the seed crystals are added while the mixture is in the metastable phase range. n Free flowing acetylthiophenyl propionic acid particles are obtained. The invention also relates to such particles. |
