| titleOfInvention | Method for preparing oxytetracycline hydrochloride |
| abstract | The invention provides a method for preparing oxytetracycline hydrochloride. In the method, oxytetracycline is used as an initiative raw material, hydrochloric acid and methanol are used as co-solvents, and active carbon is used for decolorizing. A finished product is obtained by salt formation under the action of dry HCL, dynamical stirring, cooling and crystallization, crushing and screening of a wet product and airflow drying. The oxytetracycline hydrochloride prepared by the preparation method accords with the standards of Chinese Pharmacopoeia, United States Pharmacopeia, British Pharmacopoeia and European Pharmacopoeia, the methanol residue is superior to ICH requirement, and the yield reaches over 95.5 percent. |
