| Abstract: | A method of recovering 2-mercaptobenzothiazole and synthesizing 2,2-dibenzoyhiazyl disulfide from waste residue of cefotaxime sodium had been developed.The yield of DM reached 23.8 % of waste residue and the product quality could meet the standard of HGB2-158-61.The results of small-scale test proved that this method was characterised by reliable technique,reasonable technological process,stable and easy operation.h could not only reduce environmental pollution,but also recover useful chemical materials,therefore it had good environmental and economic benefits. |
