通过筛选成盐剂和改变体系溶剂配比,优化了头孢噻肟钠结晶工艺条件,新工艺所得产品含量高,溶液颜色和产品澄清度均有明显提高,颗粒偏大且分布均匀,易干燥和产业化。 By screening salt-forming agent and changing the solvent ratio of the system, the process conditions of cefotaxime sodium crystallization are optimized. The content of the product obtained by the new process is high, the color of the solution and the product clarity are obviously improved, the particles are large and distributed evenly, Industrialization.
