| titleOfInvention | A kind of preparation method of DL-Lys |
| abstract | The invention provides a kind of method preparing DL-Lys for raw material with chirality lysinate, specifically chirality lysinate is dissolved in aqueous acetic acid, adding salicylide or benzaldehyde as catalyst, intensification racemization, after racemization completes, decompression distillation is except solvent, with washing with alcohol, obtain DL-Lys salt, through ion exchange column desalination, concentration, obtains DL-Lys solid after decolouring. Production cost of the present invention is relatively low, and technique is simple, not easily pollutes in production process, and L-lysine hydrochloride racemization rate when this method, up to 100%, obtains DL-Lys finished product purity more than 98%. |
