Method for purifying crystalline substance |
| abstract |
A method for purifying a particular substance contained in a mixture, comprising the following steps (1) and (2a) or (2b) and permitting a particular substance having high purity to be relatively simply recovered in a high yield from a mixture containing the same: (1) subjecting the raw material mixture in a liquid form or a slurry form wherein part of the particular substance has crystallized to crystallization under high pressure to increase the amount of the crystals of the particular substance to prepare crystals enriched with the particular substance; and (2a) dissolving the crystals enriched with the particular substance in a solvent capable of well dissolving the crystals and subjecting the solution to crystallization under cooling to recrystallize the particular substance; or (2b) washing the crystals enriched with the particular substance with a solvent capable of dissolving the crystal. |
