| titleOfInvention | Oxytetracycline-2, 5-dihydroxy benzoic acid eutectic crystal and preparation method thereof |
| abstract | The invention provides a terramycin-2, 5-dihydroxy benzoic acid eutectic and a preparation method thereof, the terramycin-2, 5-dihydroxy benzoic acid eutectic is prepared from terramycin and 2, 5-dihydroxy benzoic acid, and the powder X-ray diffraction pattern of the terramycin-2, 5-dihydroxy benzoic acid eutectic has characteristic peaks at diffraction angles of 2 theta of 8.4 degrees +/-0.2 degrees, 12.0 degrees +/-0.2 degrees, 14.4 degrees +/-0.2 degrees, 15.7 degrees +/-0.2 degrees, 16.8 degrees +/-0.2 degrees, 17.5 degrees +/-0.2 degrees, 18.7 degrees +/-0.2 degrees, 19.1 degrees +/-0.2 degrees, 21.5 degrees +/-0.2 degrees, 21.7 degrees +/-0.2 degrees, 22.5 degrees +/-0.2 degrees, 23.0 degrees +/-0.2 degrees, 23.2 degrees +/-0.2 degrees, 24.1 degrees +/-0.2 degrees, 24.9 degrees +/-0.2 degrees, 26.8 degrees, 27.8 degrees +/-0.2 degrees, 29.2 degrees +/-0.2 degrees, 30 degrees +/-2 degrees, and 2 degrees. Compared with the existing oxytetracycline, the oxytetracycline-2, 5-dihydroxy benzoic acid eutectic of the invention has more stable physical properties, the water solubility of the oxytetracycline-2, 5-dihydroxy benzoic acid eutectic is obviously improved under the same conditions, and the prepared oxytetracycline-2, 5-dihydroxy benzoic acid eutectic has good stability. |
