Embodiment 1
[0020] Example 1: Preparation of Cefuroxime Sodium
[0021] Add 200ml of acetone and 30ml of purified water to a 500ml three-necked bottle, put in 40g of cefuroxime acid, stir at a temperature of 25°C until it is completely dissolved, add 4g of activated carbon, filter with suction, and add a completely dissolved solution to the filtrate at a temperature of 25~-30°C. The mixed solution of sodium isooctanoate, sodium acetate and sodium lactate was added and stirred for 15 minutes, 600ml of acetone was added dropwise to crystallize, slowly stirred for 30 minutes to grow the crystals, suction filtered, washed with acetone and dried for 2 hours to obtain the finished product of cefuroxime sodium. The content is 94.8%, and the maximum impurity is 0.2%.
Embodiment 2
[0022] Example 2: Detection of Cefuroxime Sodium Product Properties
[0023] Five batches of cefuroxime sodium products were prepared according to the preparation method in Example 1, and the batch numbers were Y0810001, Y0810002, Y0810003, Y0810004 and Y0810005, and the following items were tested for these five batches of cefuroxime sodium products. The results are shown in Table 1
