| Questions And Answer | Back Directory | [Preparation]
The existing synthesis process for levofloxacin hydrochloride involves a condensation reaction of levofluorocarboxylic acid and N-methylpiperazine under a catalyst to produce levofloxacin. The solvent is then evaporated, and the product is crystallized in a crystallization solvent and dried to obtain dried levofloxacin. Finally, levofloxacin is salted with hydrochloric acid and crystallized multiple times with ethanol to obtain levofloxacin hydrochloride. The existing synthesis process has the following problems: 1) It requires the prior preparation of levofloxacin crystals before salting with hydrochloric acid, making the process lengthy, cumbersome, and difficult to operate; 2) The use of a catalyst in the preparation of levofloxacin introduces impurities, resulting in low purity of the final levofloxacin hydrochloride, requiring further purification. |
