| titleOfInvention | Method for purifying optically active lysine |
| abstract | PURPOSE: To purify and separate crystals of optically active lysine in high purity, by converting a solid or solution of the optically active lysine containing DL- lysine into a solution state containing DL-lysine hydrochloride crystals present therein, separating the above-mentioned crystals, and depositing the crystals of the optically active lysine from the mother liquor. n CONSTITUTION: A solid or solution of optically active lysine containing DL- lysine is converted into a solution state containing DL-lysine hydrochloride crystals, which are then separated. Crystals of the optically active lysine are then deposited, separated and purified from the resultant mother liquor. If the raw material to be purified is the DL-lysine hydrochloride, the DL-lysine hydrochloride is deposited by concentration or cooling crystallization, etc. If the free DL-lysine is used, an adequate amount of hydrochloric acid is previously added thereto. Hydrochloric acid is removed from the mother liquor after separating the above-mentioned hydrochloride or neutralized, and the crystals of the optically active lysine are purified by concentration or cooling crystallization thereof or deposition with an added organic solvent, e.g. an alcohol. n COPYRIGHT: (C)1985,JPO&Japio |
