头孢菌素C反应性萃取的初步研究.Ⅰ.萃取体系的选择

Study on reactive extraction of cefalosporin CⅠ.Selection of extraction system

对季铵盐７４０２反应性萃取头孢菌素Ｃ的性能进行了系统研究。通过对萃取剂、稀释剂、助溶剂的比较和筛选。

The reactive extraction of cefalosporin C with quaternary ammonium salt 7402 was systematically studied. By the comparison and screening of the extractants, the diluents and the auxiliary solvents, the extraction system of 7402-20% ( V/V ) octanol-n butyl acetate was determined.
