Embodiment 1
[0035] Embodiment 1: the preparation of cefoperazone sodium compound
[0036] making process:
[0037]Measure 500ml of ethyl acetate and 100ml of water and add them to the standing wave reactor of the hydrodynamic principle device. While stirring, 25.01 g of sodium carbonate was slowly added. Adjust the pH value to 6.2. After the pH value is stable, add 0.21 g of activated carbon, decolorize for 30 min, and filter. Wash the carbon cake successively with acetone 50ml×2 and water 50ml×2. The temperature of the solvent circulation tank is controlled at 18-20°C, the temperature of the standing wave reactor is controlled at 30-35°C, the circulation pump is turned on, and 300ml of acetone is added dropwise to the standing wave reactor. Crystallize for 30min. Slowly lower the temperature of the solvent circulation tank to 8-10°C, turn on the circulation pump, continue to add 50ml of acetone dropwise, turn off the circulation pump, and stand for crystallization for 2 hours. Sucti...
Embodiment 2
[0039] Embodiment 2: the preparation of cefoperazone sodium compound
[0040] Measure 600ml of ethyl acetate and 100ml of water and add them to the standing wave reactor of the hydrodynamic principle device. While stirring, 25.02 g of sodium carbonate was slowly added. Adjust the pH value to 5.1, and after the pH value is stable, add 0.20 g of activated carbon, decolorize for 30 min, and filter. Wash the carbon cake successively with acetone 50ml×2 and water 50ml×2. The temperature of the solvent circulation tank is controlled at 15-18°C, the temperature of the standing wave reactor is controlled at 30-35°C, the circulation pump is turned on, and 300ml of acetone is added dropwise to the standing wave reactor. Crystallize for 30min. Slowly lower the temperature of the solvent circulation tank to 5-8°C, turn on the circulation pump, continue to add 50ml of acetone dropwise, turn off the circulation pump, and let it stand for crystallization for 2 hours. Suction filtration, ...
Embodiment 3
[0042] Embodiment 3: the preparation of cefoperazone sodium compound
[0043] Measure 400ml of ethyl acetate and 100ml of water and add them to the standing wave reactor of the hydrodynamic principle device. While stirring, 25.04 g of sodium carbonate was slowly added. Adjust the pH value to 6.5. After the pH value is stable, add 0.25 g of activated carbon, decolorize for 30 min, and filter. Wash the carbon cake successively with acetone 50ml×2 and water 50ml×2. The temperature of the solvent circulation tank is controlled at 10-15°C, the temperature of the standing wave reactor is controlled at 30-35°C, the circulation pump is turned on, and 300ml of acetone is added dropwise to the standing wave reactor. Crystallize for 30min. Slowly lower the temperature of the solvent circulation tank to 2-5°C, turn on the circulation pump, continue to add 50ml of acetone dropwise, turn off the circulation pump, and let it stand for crystallization for 2h. Suction filtration, and the f...
