The Reuse of Dregs Generated in Cefotaxime Sodium |
| |
Abstract: | Mercaptoben-zothiazole (M) was recovered from dregs generated in the production of cefotaxime sodium,and was used to synthesize 2-dibenzoyhiazyl (DM) which was one of materials in the production of cefotaxime sodium.The yields of M and DM reached 25.5% and 23.8% of dregs,and the quality of products could meet the standards of HGB2-157-61 and HGB2-158-61 respectively.This method had good environmental and economic results. |
