| titleOfInvention | Method for recovering 5- (5-oxohexahydro-1H-thieno [3,4-d] imidazol-1-yl) pentanoic acid |
| abstract | (57) [Abstract] (Corrected) [Problem] Crystals precipitated from a recrystallization mother liquor obtained by separating crystals are easily adhered to the wall surface of the concentrator and easily -(5-oxohexahydro-1H-thieno [3,4- d] A new recovery method capable of recovering imidazol-1-yl) pentanoic acid is provided. SOLUTION: 5- (5-oxohexahydro-1H- Crude crystals of thieno [3,4-d] imidazol-1-yl) pentanoic acid were dissolved in water or a mixed solvent of water and alcohols and recrystallized, and then the crystals were separated and recrystallized thus obtained. 5- (5-oxohexahydro-1H-thieno [3,4-d] imidazole-comprising washing of the crystal mother liquor with an organic solvent that separates from water and concentrating the resulting aqueous layer. 1-yl) A method for recovering pentanoic acid. |
